I attempted my F4 repin.

[Slammed95S14]

While waiting for parts, I decided to give the F4 plug a shot. I used a source that seemed to be correct. I'm not asking anyone to do this for me and give me all the pinouts. I just want someone who knows the repin process to look at my plug and see if I have repinned it correctly. Send me a message if you see something, and I will send you my current re-pin.

Thanks alot.

Here's pictures.

I used this source.

EDIT: Just realized my chart is for 96 Ignore the M plug pinout i setn you as its for a 96. F4 is reliable as long as you have a Zenki engine. I sent you my chart which has worked for me more then 4 times. I also strongly recommend repining it and not cutting it like some people have been doing. It will be more reliable and takes less time and looks clean.

Also it is my personal opinion that its better to name pins what FSM calls them. "Ign Sw" instead of power with key on or some $hit like that. This way you will never get them mixed up with something else just because you have a brain fart that minute.

if you make the tags smaller it will be SOOOOOOOO much easyer to work with.Mine is missing tach and water temp bc i had to trace them from ecm due to missing FSM SR pages so i didnt get a chance to update it along with couple others, but all the basics to get it running are there.

Oh and ignore the lil notes i put down for my own reference.

Thanks. I'm confused on what is what. What am I supposed to repin where according to your table.

[Acuratechva]

Repin F4 to match F3

KA Pins are labeled S bc FSM calls them that way...why i don't know, but i did it anyway.

Wire locations are as if you were looking at the plug from pin side not the wire side.

F4 as you know are the SR harness plug. Wires on KA and SR F plug are numbered differently. KA has 1 pin on the "thick side", SR on the thin side. this makes things very confusing for a lot of people and if you are looking at the plug wrong liek from the back instead of front you will get the wrong pin.

F4-sr plugF3-ka plugM-63 ka body harness plug but dont look at it as it will make things more confusing. Following example will not match up with my chart bc its for a 96, i looked up fuel pump for a 95 for the example.

Here is an example to do the fuel pump. You need to:1. find the pin on F4 plug which is 22 B/Y.2. look up fuel pump diagram(ka), page EC201. its pin 27 B/P. Color of KA wires is irrelevant i am just putting it down for reference. All you are concerned with is the location.3. look on the diagram of the F3 KA plug and find where that pin is on the F4 plug.4.i am going to say this one more time so you don't forget, pin 22 on F4 and pin 22 on F3 are not in same location because as i said earlier number one starts on different side of the plug.5.now take SR wire(b/y) and move it where pin 27 would be according to the F3 chart.(if going by F4 diagram only move it to 14)

Dont forget besides doing the F4 you need to move the wiper motor plug pins to match that of US plug. if you look at both diagrams you will see what i am talking about.

Thanks alot! I will double check everything tonight and fix what is incorrect. I owe you alot. Thanks for taking the time to explain it!

[Nicen96]

I am about to do the same swap but I have a 96 240sx se and a 98 sr20det black top is this the same for me. Thanks a bunch

[Acuratechva]

it probably is. go over my chart for the F4 and see if the collors match. Only fsm that's floating out there is for the zenki models and it may be different, but nobody has been able to confirm it. Kouki and Zenki in US have diff pin locations for the F3/f4 so i would not be surprised if some didn't match

let me know if you need me to double check any pins or you're missing one

then please let us know. take close up pics of the plug from both sides like Slammed95S14 did. Its in my best interest to help you, as i want to swap a Kouki SR in my new s14 and would love to avoid these problems, so don't hesitate to email me.

PS i will be in NY 8-12 so email response will be limited to night time if not at all.

[Nicen96]

So do I have to use the KA harness or can I repin the SR harness.

[Acuratechva]

you need nothing from the KA harness UNLESS you have a kouki in which case you will need to use the wiper motor plug which is physically different, but still same 6 pins. in your case it will be opposite.

tips:most of Wiper wires will match up and wont need to be moved but as always double check. i say that because every time i do the wiring i forget about it . so i end up pulling them out of the plug , then realize they are suppose to be in same location and put them back in... waste of time.

three thick B/R(black with red stripe) wires will need to be soldered together. just pick one of them and solder the other two to it. When you do that solder them away from each other and at least 2 inches from the F plug. this will give you more flexibility in the harness and prevent breakage later on .

when you get ready to cut the pins of two of the black/red wires cut them as far from pin as you can you will need them later

One of the wires from thin side of F plug will need to be moved to the thick side. i THINK its the wiper washer motor but i am doing it by memory so don't quote me on that. Use the piece of pin/wire from above step here.

i know this is obvious, but avoid using electrical tape, stick to shrink wrap its worth it.

Ok I just got some time to go and look at my F4 pin. On your chart that you have 40 is listed twice and 29 is listed three times. Also there are several places I have no wires at on my F4 plug like 40,31,47,24,39, and 23 I believe thats all. Here is what I have for my F4 plug see if you can help.Also I am guessing that L is light blue.1-PU 25-R2-L/Y 26-NO WIRE3-L/B 27-O/B 4-Y 28-O5-Y/G 29-BR6- NO WIRE 30-O/L7-NO WIRE 31-B/Y8-G/B 32-R9-B 33-NO WIRE10-B 34-NO WIRE11-B/W 35-NO WIRE12-G/O 36-NO WIRE13-NO WIRE 37-L/R14-NO WIRE 38-NO WIRE15-G/W 39-NO WIRE16-NO WIRE 40-NO WIRE17-G/Y 41-BR18-G 42-LG/R19-G/R 43-LG/B20-O/L 44-LG21-NO WIRE 45-P22-B/Y 46-NO WIRE23-NO WIRE 47-NO WIRE24-NO WIRE 48-B/R This is a brand new harness from courtesyparts.com and its for a s14 but I dont know if its a for a 95,96,97, or 98. Do I just make my harness like yours or what is the deal. Thanks for the help.

[Acuratechva]

Remember , my chart is by component for easyer diagnosis. If i have 29 listed twice that means more then one component gets its power from that pin so if you see it listed more then once keep note of it but other then taht ignore it.

I did not take note of empty pins i only put down what matters.

I checked first 4 and they match up with my F 4 plug, but i dont have time to check the rest and it may not make much sence===>refer below...all i am saying is, its pointless to try anything until we know what were dealing with

You not knowing your Harness type i not good. BC if they sent you the Zenki and you have kouki wire collor may match up but MAY not go different places.

rhdjapan.com may have part numbers go loook on there and compare to your harness.What is the ECM label? RED WC or Black WC?Does the MAF plug from harness plug in to your maf? is it a push to release plug or does a "clip/pin" need to be removed?

call courtesey parts and fin out which harness you have.

[Nicen96]

So do you think you will be able to figure out why my wiring is so much different than yours. Thanks for giving the info that you did.

[Nicen96]

The plug that plugs into my ECU is blue if that helps any. I wont need my mafs sensor because I am getting an AEM EMS and going map sensor so i sold that a while ago on here.

[Acuratechva]

email me, it is easier to communicate that way and send me pictures of the F plug(both ends) such as above so i can see it first hand.

[Acuratechva]

i looked at your pins again and some match some dont. where you say blank there should be a wire. not to say you are wrong but send me a picture of the plug from both sides of it. then i will be able to tell you for sure.

also why is it missing half the pins? out of 50 you gave just 23. and i have no need for the ka plug just SR. wire colors in my chart for the KA are for reference/diag only

email from now on

WOW THATS.......
