Ok, so as most of you know I did this swap recently. I looked all over the internet for people who had done the swap and how to wire it. Well after trying what I found on my own I realized how wrong most of the "free" information was. I didn't want to buy a wiring DVD and I also didn't want to spend $350 to have the wiring done by someone else, when I know I could do it on my own. So being armed only with the Factory Service Manual's (FSM) for both cars I wired it all on my own. With that being said I am going make a disclaimer, this is the way I did it in my personal car, some may have done it differently than I did. However my car runs great has no check engine light/fault codes. Also for the SOHC owners out there... the write up will work for you but you will need to pinout your own SOHC S13 interior plug. However, the wire colors are the same on both DOHC and SOHC interior plugs. This means you should be able to match up my diagram with the correctly colored wires on your SOHC plug. Also the SOHC cars will need a DOHC Tach/cluster in order to read the tach signal of the SR. Now for the full disclaimer.
***I AM NOT RESPONSIBLE FOR WHAT HAPPENS TO YOUR CAR IF YOU USE THIS GUIDE, IT IS FOR INFORMATIONAL PURPOSES ONLY!***
Ok to start off, my swap was from a JDM Zenki S14. They are the 1st generation S14 motors so this guide is for these motorsets only. The mechanical portion of this swap is all bolt on and drop in, meaning the motor/tranny mounts are all the same for S13, S14 and S15. So the motorsets will fit no matter what chassis they are in. The stock KA drive shaft fit fine, however I had to remove the tranny dust cover in order to push it all the way into the tranny.
Start with pulling the stock KA motor, trans, wiring harness and ecu. All the smog equipment on the KA can be removed with the exception of the charcoal canister. Leave that behind since it's doesn't affect power/reliability and is used for removing fuel vapors from the fuel tank.
Here you see I removed the hood for more clearance.
Here are the S13 power plugs that lead to the KA ECU, these need to be spliced into the S14 power wires.
Behind the glove box you can see the interior plug for the DOHC S13 motor (it's the brown plug) and this will be spliced into the S14 interior harness wires. On SOHC cars this plug will be white. Ignore the ****ty stereo wires as they were there before I bought the car lol.
More parts removed from the car.
Once everything is disconnected from the car you can loosen the motor/tranny mounts and pull it from the car.
Now we are ready to put the SR in. At this point remove the S13 KA temp sender from the the KA motor, it is a single pin sender located on the coolant inlet of the intake manifold. Then take the temp sender from the S14 SR out, which is located under the throttle body. Replace it with the KA temp sender. This will make your temp gauge on the dash function correctly.
Here you can see I removed the stock clutch fan because I have no use for it since I already have a set of Altima eletric fans.
All done and bolted in!
Here are the stock SR heater hose lines. As you can see in the pic these can be cut and routed right to the stock USDM S13 heater core connections. I chose to use the hoses that came with my swap since they were in great condition. However there are a set of hoses you can get that are prebent and fit the S14 SR heater location perfect. I will posts those numbers later.
Here you can see the stock S13 throttle cable lock nuts are too small for the S14 bracket which is why the S14 grommets must be used.
These are the stock S14 throttle cable grommets, the one on the left needs to have a slit cut into it like the one on the right to work with the DOHC S13 throttle cable. On the SOHC cars I am not sure if this will work since I dont have a SOHC and the cable is a different length (IE: you may need to get a DOHC KA throttle cable).
This is the grommet after it has been modified to slip over the throttle cable.
Throttle cable installed and routed. Also you can see the DOHC KA brake booster vacuum line, all you need to do is trim it to length to fit the SR motor.
My new Koyo S13 SR20 radiator, an SR20 rad is needed cuz of the different inlet location on the SR vs. KA, otherwise you will need to make a crossover tube. Beware tho, SR's like to run hot especially when they are running on a stock KA rad. You should really run a better radiator for this swap.
At this point you can hook up the power steering lines, on the DOHC S13 the high pressure line will fit perfect, however the return line will need to be trimmed to length to fit the SR pump location. From what I have been told on the SOHC cars you can simply buy the DOHC high pressure line and swap it over.
Here is where it gets a bit interesting, the S13 and S14 SR motor's have different plumbing/routing for the charge pipes. The BOV's are on different sides and the stock SMIC's sit in different spots too. So you can use the S14 SR charge pipes but you will have to drill holes and make your own mounts to make it all fit and work. In my case I already had an S13 Greddy FMIC kit, so I ended up using a combination of the stock S14 hot pipes and the Greddy piping as well. Then I bought an after market S14 piping kit to complete the piping for my motor. Some people say buy the S14 Greddy kit and you're good but again not all of the piping fits right either. So you're pretty much gonna need to custom cut/make all the charge pipes.
I had to reposition my battery to drill a 3 inch hole for the intercooler piping to pass thru.
Now for the really fun part... the wiring.
Ok since I didn't want to kill a good KA wiring harness I opted to get a spare wiring harness. You are basically going to fully destroy your KA harness and rape it for connectors/shielded wires. If your ok with this then use your harness, otherwise get a spare one. The good part is the power plugs are the same on the KA DOHC and SOHC harnesses, the bad part is the interior plug is different on them. So you really need to a harness that fits your chassis.
The lower engine harness for the KA will plug right into the S14 SR motor, all you need to do is drill to enlarge the hole on the KA Alternator power wire ring terminal to fit the size of the stud on the S14 SR Alt. The S14 SR tranny plug ends will need to changed over to the S13 plug ends or vice versa, I decided to just change the plug ends on the tranny sensors so that I could reuse the lower harness on my S13 KA tranny later. Some people say you can simply take the sensors from the S13 tranny and use them on the S14 tranny... I have not verified this but it does appear that they can swapped. The Speed Sensor from the S13 Tranny must be used since the S14 will not read the right speed.
At this point we have to wire the main harness... it's not as hard as it seems but it was a PITA for me to do since I ripped my harness apart using other wiring info on the net which turned out to be WRONG! So I had to repair my harness first, then deloom it entirely and wire it up my way.
Where you should start is by delooming and rerouting the harness connections on the motor to fit the LHD configuration of the USDM S13 chassis. Route it however you want... but you must do this first. This is so you know what wires need to be extended to meet their respective connections. In my case I extended the MAF, Boost Solenoid, Power Steering Switch and I also added the stock Boost Pressuse Sensor connection to come out by the TPS plug. I also changed the S14 SR power steering switch plug over to the the KA plug to fit my KA power steering switch.
On a side note the stock boost pressure sensor is plugged into the S14 SR's fuse box, make sure you get this sensor and plug end when you buy your motorset. I am not sure if this is needed to make the car run right, but from what I read in the S14 SR F.S.M. it seemed to be an important part so I added it to my harness. The boost pressure sensor is easy to wire, all you have to do is tap the power and ground from the TPS to the power and ground from the pressure sensor they are the same colors. This is the way it was from nissan as well, just the location of the sensor is different. Then with the remaining signal wire extend and run a sheilded signal wire back thru the wiring harness to the white wire on the S14 SR interior plug, this leads to Pin 35 on the ECU. Make sure that you use a shielded wire for all the signal wires, you can get shielded wires off of your old KA harness.
Here is the S14 wiring harness unmodified.
Here is the harness after I deloomed part of it, the blue plug with the larger gauge blue wire is the ignition coil relay, the other is the ecu relay. Finally the white plug is the S14 SR interior plug, this is where most of your connections will be made.
USDM S13 DOHC and SOHC power plugs. The main power wires are the same color on both DOHC and SOHC harnesses, however not all of the wire colors are the same color, but regardless of color of the wire the position of each wire does the same in both cars. You want to deloom this harness and keep as much of this wiring as possible by cutting the wires at the ecu plug. These wires will be reused to power the S14 SR harness, you will route the power wires the same way as they were stock in the stock S13.
USDM S13 DOHC brown interior plug, again the SOHC plug will be white. This is what you make the S14 Sr harness look like so that it will plug into the S13 Chassis. 
All of the wiper motor/amp wires can be removed from the S14SR harness as they are not used, at all on the S13 Chassis. Also I did not wire up the A/C because I don't run A/C in my car, however it should be super easy to connect the correct wires using the wiring diagram from both F.S.M's.
Now we come to the actual wiring of the harness. I made this in the easiest format I could, hopefully everyone understands it. Additionally I made the same wiring diagram in microsoft word for download and I also included the microsoft excel pinouts that I used to help wire my car. The links for these files are below.

When you get to the S14 SR wiring harness firewall boot, you will need to pull all the tape off of it and then you can slide the boot out of the way. Once you get the boot moved you will see a bunch of black goop all over the wires, you will need to individually pull the wires out of this black stuff so you can move the boot to where you need it to be on your harness. Now you can loosely tape up the harness so it fits everything right, then connect everything to the car and motor. The reason I say to loosely tape it is so if something is wired wrong it will not be hard to go back untape it and make the corrections.
Now once you have plugged everything back in to where it goes, ***MAKE SURE YOU HOOK UP ALL THE GROUNDS***, finish all the charge piping, vacuum lines and fill with fluids. If you wired it right, the ECU & IGN coil relay's will click when you turn the key to the 'ON' position, as well as you should hear the fuel pump priming the fuel lines. If it all works you can try to start it. My motor is wired this way and fired up on the first try. Hopefully your's will too! Once you get it running good and there are no check engine lights then you should be able to tape/loom everything back up and finalize all the installation.

If you have done the factory troubleshooting steps and still no spark I would try a different ecu. If you have not done the troubleshooting then I would get the FSM and start diagnosing. Also make sure all the grounds on your engine are connected, 2 ground plugs on the engine harness go to the intake mani, then one from the negative terminal on the battery to the intake mani, one on the lower engine harness to the alternator and one from the back of the head to the metal prong on the firewall.

No like I said before the boost pressure sensor is plugged into the factory JDM S14 SR fuse box, the sensor itself sits off the side of the fuse box and has a vacuum line that runs to the cold pipe elbow.

I noticed that you didnt relocate your battery when you did your swap. When I relocated mine I ran the power side up to the factory battery location and hooked the negative side to one of the rear seatbelt mounts. Maybe thats not a good enough gound location to let the coils fire. I dont know. In my last ditch effort for spark I'm going to run a wire straight from the negative side of the battery to the grounds on the intake mani and the main engine ground.
If that doesnt work I am seriously going to rip the engine out of the car with a tractor and use it for .50 cal practice. Then I'm going to pick the car up with the tractor and dump it on its roof... repeatably.

As far as canister's go there is a black canister on the left side/drivers side of the car that is the carbon canister. The only canister I can think of on the right side/passenger side would be the aluminum reciever/dryer for the a/c system.
Which part of my diagram is confusing?

From the pic you posted the stock boost solenoid is gone and a manual boost controller was pot in it's place. The Singal wire connector that you labeled #1 I am pretty sure it's for the A/C compressor which I removed, it should be a blue/red wire if it's for the compressor.

| Hi, I am presently doing the Zenki S14 SR20DET swap into the S13 chassis. Just wondering how to connect the fuel lines from the fuel filter. There are 2 fuel line connections side by side on the S14 motor. Can you tell me which line should be connected together with the fuel filter lines? Also, the black hose that runs across the top front edge of the valve cover, what is it for and how should that be connected? Thanks in advance for your help! |
The return line goes to the fuel pressure regulator side of the fuel rail. Also are you talking about the black plastic hose on the front of the valve cover? If so that is for the factory blow off valve to recirculate the expelled air back into the intake tube.
Thanks for the compliments everyone!

At any rate, I would just like to add that you must wire ECU Pin 45 to a switched 12v+ power supply (black red ~ Pin 40 on interior plug with mestizo's numbers). Without it, the ECU will not turn on, no spark , no fuel , no relays. I used the switched 12v+ for the ignitor relay.
I spent the better part of an afternoon scratching my head trying to figure out why an ECU with power would not turn on. 
Cheers,

The SOHC and DOHC plugs are NOT the same. Pinout is opposite for the SOHC and DOHC. I found this out by spending $100 on a DOHC KA harness since the write up was done on that (my car was a SOHC) . Got everything wired up and the interior plugs do not connect. I have a DOHC plug on s14 harness and a white interior plug on the car and they do not line up, in fact they are opposite. Fu*k Me once again. i can never do anything right. Had all my connections soldered, shrink wraped, and taped. Now its going to look like sh*t. AWESOME!!!!!!

Posted by: mestizo at 12:02 PM 11/22/2008
However its really an easy fix. You can depin your Brown DOHC plug on the end of your newly made S14->S13 harness and then do the same for the sohc white plug from your original SOHC harness and switch the plugs. All you need is a small tip screw driver or pin to depin the connector's, then just slide them back in and youre done.
Also you can start the car without the interior plug being hooked up, the only thing is it will not read any CEL codes or anything else for that matter on the cluster. It will also not add any extra feul at start up cuz there is no start signal going to the ecu. But it will crank and run. Just be careful not to run it for long without any instrumentation.

Mestizo, what appearance differences are there between the zenki and kouki s14 engines? Would it be just the wiring harness connectors or a sensor or 2 being different?

I dont think there are many difference's between the two, but don't quote me on that. As far as I know the only difference is the ecu and harness, but even that may not be much different. I think Hijacker was looking into doing the research on this.

Looking at the plug and using the numbers he has on the pinout for the interior plug it goes as follows.
1 - blue/black
2 - yellow/red
3 - yellow/green
4 - open
5 - open
6 - blue/green
7 - black with a double dashed silver line
8 - looks black but it is called dark green
9 - white
10 - orange
11 - gray/ blue
12 - red/yellow
13 - black with single dashed sliver line
14 - green
15 - red
16 - purple
17 - light green
18 - gray
now what? i got two reds and two blacks and some extra colors. Where can i find a piout for ths plug and find out what each one is so i can match them up?

| THe interior plug wire colors should be the same on the sohc interior plug so all you would need to do is match color for color. |
Yes the 6 wires nesessary are the same but the (optional) ones are not. And there are more wires on the SOHC then the DOHC interior plug. I just used the six and hooked everything up. Now im just routing the wiring harness. Looks like the only thing i'll need to extend is the WAF wires. The boost control solenoid and ignitor wires were way short so i think im oing to run the whole assembly to the passenger side where the wires reach and just extend the vacuum lines. Should be running this weekend!!

Now there are 4 plug connectors that go into the ECU, the most basic way to tell is to look at the 2 middle plugs. On a zenki harness and ECU the middle left and middle right plug will have 10 pins across like so:
Middle left plug:
. . . . . . . . . .
. . . . . . . . . .
Middle right plug:
. . . . . . . . . .
. . . . . . . . . .
On a kouki it will look like this with 7 pins on the middle left plug then 8 pins on the middle right plug going across:
Middle left plug:
. . . . . . .
. . . . . . .
Middle right plug:
. . . . . . . .
. . . . . . . .
I have a Zenki, oh well. 
Merry Christmas everyone!

There should be one ground from the intake mani to the chassis, one from the back of the head to the chassis, 2 on the back of the intake manifold that go into the engine harness, 1 off the back of the coil packs which grounds to the head, 2 off the lower harness 1 that grounds to the alternator and 1 that grounds to the chassis and finally make sure the battery ground to the chassis is clean.

The one i dont see is the lower harness to the chasis. I checked my stock 240 w/ the KA and couldnt see one either. Is this incorporated into one of the plugs by the battery? Cuz i deffinitely did not see one directly from the lower harness to the chasis. Im going to go see if im getting power to the ECU.

As for tha ground, i dont even have that eylet on the harness. I used the KA harness and checked with my other KA which also doesnt have that ground wire. The s14 lower harness does have it but it runs directly to the starter i believe or alt. Either way like you said this should be the problem.
I cant think of anything else it coul be. I followed your instructions to the T. Everything was soldered with flux, shrink wraped, taped, and loomed.
My friend thinks its a bad ECU but i doubt it. Where can i start testing stuff with the volt meter to trace the problem? Thanks. Should i just e-mail you insted rather than clog up this thread? Would that be easier?

the ground shown in the pictures above is an extra ground for the ALT. it helps to suppress radio noise.
Check to see if you are getting power at the BLK/RED wire at the big grey plug by the battery
Check to see if you are getting power at the BLK/WHT wire at the big grey plug by the battery
test these with the key in the ON position
if not, turn the key to ON and ground out the RED/BLK wire on the brown plug by the battery
the RED/BLK wire is the wire that comes from the ECU to trigger on the ECCS relay that powers up the engine harness. it does this when it the ECU sees voltage from the BLK/RED. this will be a good frist step.
also check for power (key ON) at the large BLU/RED wire at the coil pack harness.

| The boost pressure sensor shouldnt stop it from starting up and running, and when you did the wiring did you keep the S14 power relays or did u get rid of them? The reason I ask is cuz if you cut them out then this is why you have no power. I made this write up to keep the relays in place all you do is give them power from the S13 plugs. You can ask me questions here or e mail me, either is cool. |
If your talking about the 2 blue relays ECU and IGN relays, Yes i did keep them and did the wireing as per the write up.

Ok. With the key on i get 12V at the BLK/RED wire at the big gray plug. I get 0.1-0.3 at the BLK/WHT wire at the big gray plug. Nothing at the BLU/RED wire at the coil pack harness. In fact i didnt even see a BLU/RED wire there. I have, on the harness side, not the plug coming from the coil packs, LT BLUE, GREEN, PINK, WHTE, and RED.
when i grounded out the RED/BLK wire on the brown blug, i herd all the relys in the engine relay box clicking, and i then got 12V at both the wires in the gray plug.
So, whats this all meen now?
And whats with the not needing the relays? Should i unplug them?

| using the S14 SR relays is completely useless as the S13 chassis has those relays already. this can cause some confusion if not done properly. |
Yup they are not needed but I decided to keep them so there was less to modify on the harness. To each their own and I am not really sure how much confusion leaving them there can cause.
92vert240:
In my write up I used only the Blk/Red (Ign Switched 12v)and Red (12v Constant) on the S13 grey plug to power the S14 harness, these are connected to the S14 interior plug and in turn lead to the Blue Relays on the S14 harness. The red wire powers the S14 ECU relay which in turn triggers the coil pack relay which is powered by Blk/Red wire... this is the way it was form Nissan.
The only other "power" providing wires is the Brown wire on the S13 brown plug to the Brown wires at pins 21 & 48 on the S14 interior plug, this is the wire that provides all the injectors/sensors on the motor with 12v switched power. As well as the Blk/pink on the S13 brown plug to the pin 30 Black/Yellow wire on the S14 interior plug, this is the fuel pump trigger.
So basically as long as those get 12v at the right times then the harness is fully powered as long as you have it grounded.
I just took a pic of my S14 SR interior plug and there are a few wire colors on it which were duplicated from Nissan so there is a chance that you may have connected to the wrong wire by accident. There are 2 black/yellow wires that are for the most part right next to each other. Also 2 black/red wires next to each other. So please go back and double check which wires you spliced into.
I will provide pics for you in a few mins when I get them all worked out.

you are painfully incorrect here. the brown wire only supplies power to the O2 sensor and to the wastegate control solenoids. thats it. and the black/pink wire is the ground trigger for the fuel pump relay. the blak/yellow wire is the switched power wire for the idle air controller.
where are you getting your info? no wonder this kids car isnt running.
as far as the OP, sorry i forgot you had an s14 SR for a moment, it will be the fat BLUE wire on the coilpack plug. you obviously have your red/black wire run incorrectly. take the red/blak wire from the brown plug by the headlight, run it into the car and hook it up to the red/black wire going to the S14 relays.

| Also try this since another member on here made a comment about it, put 12v switched power from the brown S13 plug wire or any other 12v switched source to the Blk/Red wire at Pin 40 on the S14 interior plug which leads to Pin 45 on the ECU. I think some of the wiring harness' had a small variant or something because I did not have to do this since it was already interconnected to the S14 relay wires on my harness.

there are no 'variations' to these harnesses, only a handful of different people looking at the harness incorrectly but some how making them work. be careful on the missinformation spread.
Post Title: Re: How to JDM Zenki S14 SR20DET swap into a DOHC S13 (Taylor_Durdan)
Posted by: mestizo at 11:15 AM 12/31/2008
The reason why I say there must have been a variant in the harness is because of the fact that my S14SR harness had the blk/red wires at pins 40 & 38 on the S14sr interior plug interconnected after the interior plug. Why they were connected I don't know but it was a factory Nissan connection, stripped wire ends, metal crimp band, black electrical tape. According to the S14 SR FSM it shows them not connected, but mine was so I just took it as the manual I had was not 100% correct since it was not a true Japanese FSM. People have been doing it this way for while before the member "Whitesol" said he had an issue with it. This was the first time I had heard of those wires not being interconnected and if you took a look at my pinout it has been changed to make it so those wires get connected.
I am not spreading misinformation as you put it, I was asked by a Mod here on Nico to put my write up on Nico. This thread has been around for 9 months before you jumped into it. Also I am not about to argue about what wires go where and what they do. All I know is what the FSM diagrams and the excel pinout's say nothing more. If you don't like my wite up then make one of your own and put it out there.
If this write up bothers you that much then talk to the mods and have them tell me to take it down if you feel it is all wrong. But again I have gotten nothing but positive emails and comments about it. If they had been negative emails saying the write up didn't work I would have removed the write up. Which if you read the begining of my write up it says that I tried several write ups but none of them worked correctly which is why I ended up wiring it my way. I am not here to piss people off or give the wrong information, all I was trying to do was help out.

What I did was provide the S14 sr harness with the same power it had from the factory. So what? How is that wrong? How is that calling it something else... like a tire for instance?
If you're not here to help then stop posting. Again if my write up bothers you that much and you can prove I am wrong and spreading misinformation as you said then tell the mods about it. I will remove my post and stop trying to help others with this. That way people can send their harness to you to get done and you can get their money.
Lastly Ill say it again, I did this to help and I was asked to make this write up here on Nico. I wasn't charging anyone nor was I trying to put wrong info out there.

it was this response alone that had me in arms. telling someone to hook power to the blak/pnk wire will not only short the fuel pump relay, but fry the ecu as well. thats what i mean by not explaining it properly. you know that the blk/pnk is the same as the blk/ylw on the s14, and you know what the wire is for.. but not knowing what exactly the wire DOES can steer someone else to doing something that can ruin their project. if advice is to be given, then it should be correct.
thats my argument
__
i bust my *** to provide a clean, correct solution for problems such as this and i'm sorry if i put too much heart into what i do. after doing these harnesses for almost 10yrs, ive seen it all... and it hurts me that someone will just throw out their diagram online without fully understanding what exactly is going on. im all about the DIY'er but i also get a slew of emails bc of diagrams like these from people trying to figure out just what exactly they mean. i guess im just irritated mostly by people that have no earthly clue whatsoever on how to do something, attempt it, fail and then wonder why i have to charge more or take a few extra days to complete and repair their mistakes.
bah.. im just on an irritated ramble at this point.

"As well as make sure the Blk/pink on the S13 brown plug is connected to the right pin 30 Black/Yellow wire on the S14 interior plug, this is the fuel pump trigger."
So I can see why you would say this was wrong but at the same time I would not have even made this error in my statement had we not gotten into our lil arguement. Bottom line is my write up tells you to connect the right wires to each other for the fuel pump to work.
Without trying make myself sound like a complete a$$hole, I didn't go into much detail so that people would just follow my steps instead of doing their own steps to wiring the harness. I am sure you understand what I am trying to say.
I don't know if this will make you feel any better about putting so much work/effort/pride into what you do... But I didn't just throw a diagram together and make a write up. I was actually done with my swap for almost a month when I was asked to make my write up. Also for about a week I printed out fsm diagrams, excel diagrams, traced them out, wrote my own out and read everything I could before I decided I had a good enough idea of what to do. Some pics below will help illustrate what I am talking about.
This is not all of what I printed/used but this is what I kept after I did my research.

On a serious note...Mestiso did tons of research on this before taking it on. What he found was most of the stuff out there was incomplete and could lead people down the wrong path.
As most of you know taking the time to document stuff to do write ups takes like three times as much time to finish a project, but it makes it easy for the next guy.
I have seen Mestiso's car run, and I think I am in the car for some of the video. His car not only runs, but runs very well. Also the install is very clean.

In regards to the coil pack plug. I deloomed the wires but now need to know where they go... I have the coil harness plug from the S13(CA) harness. so ja... Any help will be appreciated.

...oh... yeah... you must understand I live in SA(south africa) If you get a decent S14 harness here your in luck... Plus I didn't buy the whole swap off someone. engine from one place harness from another etc.
Also I saw there is a difference between the US S13 interior plug and the South African one. Think mine might be the JDM version. Its a white plug not a brown one like in your pics.
Anyhow again thanx for the help.

Also my write up only works for a the USDM S13 DOHC harness to a JDM Zenki S14 SR20DET motorset, so anything else you would need to look into it further to find out what wires to use. The difference in the color of the interior plugs on a USDM S13 chassis basically tells you if it's a DOHC (brown) or a SOHC (white) harness.

After following your write up exactly, my fuel pump would not run at all. After tinkering around for a while, I found out that the black and pink wire coming from the fuel pump relay was not getting a completed circuit somewhere along the harness. Then I did a little looking up and found that it is meant to connect to pin 18t. So I just soldered the fuel pump wire right to the ECU, is this okay or does it have to pass through something before reaching the ECU?
I tested it and it primes perfect.
My next question is, using this picture could you please identify the knock sensor plug for me? Thanks
It's a long story of why I need this.

As for the the knock sensor plug it's not on the main harness, there is a sub harness that is on the motor and the main harness gets plugged into that which leads to the knock sensor and other things too.

Why on the gray s13 plug did you use RED pin 3) ECU backup power wire to power pin 24 on the interior plug insted of pin 5) ECU power Black/White wire? Pin 24 on the interior white s14 plug matches up with pin 59 Black/White wire on the ECU. This seems to make more sense. Also, shouldn't pin 49 be included in this to recieve power as well? It says ECU power on that pin aso on the ECU diagram.
The pin above thoes, pin 58 says Power Supply (back up). It seems more logical to use the pin on the s13 gray plug that says ECU backup power.
You have nothing going to pin 49 which needs power. Correct me if im wrong but this seems to be the way it should be. Thanks. Tyler.

But to answer your question I made the least amount of changes to the stock wiring as possible so that if a correction had to be made it would be easy to do. Also the way I powered the S14 harness is the same way it was powered from Nissan. I powered the factory relay's which in turn powered everything like it did when it was in the JDM S14 in Japan.

as far as why to use the red wire as opposed to the black/white... its bc the red wire is constant battery voltage and the blakc/white is ignition hot only.
when it seems like there is no way to figure out why your harness doesnt work, email me and i'll give you a good rate for the work. it will be an OEM fit, plug and play harness with zero issues

| quick question - which oil filter did you use? I bought a purolator 14477 (its for the early se-r) but it doesn't fit right - treads different. thanks for the help! |
go to the dealer with this part # 15208-65f00. it's the same oil filter as a 98 SER and a new USDM 350Z.

Post Title: Re: How to JDM Zenki S14 SR20DET swap into a DOHC S13 (mestizo)
Posted by: silviaziz at 4:59 PM 5/12/2009
I'm having a shop install my s14 into my s13. They seem to have everything figured out. The only problem seems to be with the MAF plug and MAF sensor. The plug does not "fit/hook up". I believe I have a Zenki front clip, and I know that the MAF sensor itself comes out of a Zenki (I checked the part #). I have to check to see if my engine has "fins" or not and also check the plugs to see if I have a Zenki or Kouki harness.
If I do have a Kouki harness, should i just "hardwire" the MAF "plug" into the MAF or should I purchase a Kouki MAF.
Also, if I do have a Zenki harness, then why would the plug not hook-up?
Any ideas would be very helpful.
Thanks

As for the cost of the relay at Nissan I don't know either, but I would venture to guess that they would be expensive. I bought one of the large fuses from the dealer and it was $18. lol I won't do that again, so now I just go to the junk yard and pull the relays and fuses from the cars out there.
Also how come Yuri didn't explain any of this to you? I mean if you paid for the service I would think he could explain what that relay does right?

As for the O2 sensor there is a parts interchangabilty thread on here somewhere. From my experience tho any O2 that threads in to your down pipe and has the correct plug will work. I have done this twice with no problem.

I know on the s13 interior plug the check engine lights is the red wire and on the s14 its the orange one. I just dont really understand how to get them to line up basically. Also I had my harness shipped out to get it done. But was told that the check engine light wasnt wired up.

At this point you will need to look at your harness for the CEL wire leading from the ECU and splice/connect it to your interior plug in the right position.
LOL what's with this trend of people sending their harness out to get done and then they get it back and still have to come to my thread to get help?

Yes it is funny that we come to your thread at least were keeping it alive .

What you need to make the two work is the FSM of you car chassis and then the FSM of the motor you are going to put into your chassis.

*i have a 200sx s13 91 mod LHD ca18det ok! now i have buyed a sr20det blacktop to put in the car, i have all that is needed for the swap wiring (myself) and eccu/ecu.
My question is: where do i put the Resistor?? the resistor from sr20det have only 2 wires, and i cant find where it must be connected. 
(i havent had start on the car yet, still some work toodo),
Thx for posting the wiring howto 
Regards From Norway

One last thing, could you take a pic or explain to me which heater hose goes to which port on the heater core? Lets say #1 is closest to motor, and #2 to the shock tower, now which one goes to top/bottom of heater core?

As for the S13 relays just leave them in place, they need to be there in order to make this all work.

| Hmm I am not sure what your talking about? Have any pics of what it is you are talking about? If so that will prolly help, but I also have another question, is your SR swap from an S13 or S14? |

(But what is it for, if its not a resistor)
*i cant find where the resistor (resistor pack for the injectors) belong in the (wiring/cable) to the engine.
(if i need to use it tho

forgot to mention, the blue relays dont click when u turn the key to start, but do click when you turn the key in off position. Sound about right?
*update* Im getting fuel to fpr and rail, lines are hooked up right, injectors seem to be the problem.

| Use should use the harness that matches your particular chassis, but the power plugs in the engine bay are the same on the DOHC and SOHC harness so either can be used. The difference is the interior plugs, but like I stated in the first post you can pretty much color for color match the DOHC and SOHC interior plugs or just get the SOHC interior plug pinout and use that instead of my pinout. |
thanks man! this helps me out alot.. i'm still not sure if i'm ready to try this or not yet i'm going to read it more and decide i should be able to do it but we'll see.

| relays only click as you turn the key off, so i dont know what the issue is there. I do have a multi meter so im gonna start troubleshooting in a bit. You happen to know what readings the injectors are supposed to get off the top of your head. |
The injectors see +12 when the key is on thru the red/blue wire.

Injectors are not seeing +12v at the red/blue wire on grey power plug? Its red/blue on chasis side, connecting to green/blue on harness side. I hooked the green blue which wasnt going to anything to the black/red so it would have 12v at key on. Went to fire it up, and still no fuel.

From the sound of what your describing it sounds like the connections are not correct.
