Complete wiring for RB25det into 95 S14

[300Plus]

Can we get a few more confirmations on this guide. Always good to know for sure.

Why not do it yourself? They're just looking at two pinouts and matching, you can do it yourself, and not have to worry about a mistake made by someone else.

[NOT_A_KA]

A lot of people will do it themselves. But if something doesn't work they can use this to check their wiring. The people that do it themselves the first time correctly will never search for a thread called "Complete wiring for RB25det into s14". Unless they want to help others out and share information, wich is what forums are for. Think of this as a guide for some and a check for others. Do you see any errors in it?

[Bluefire]

NO you are wrong once info like this gets around, people will simply print it out and wire it accordingly. Really why would you waste time trying to do it yourself when someone has put out an entire wiring guide already out there. Even I would just copy it if didn't know what to do.

Unfortunately when I was doing the swap into s13's and s14's I didn't have info for complete wiring. So I had to sit and research all of the wiring diagrams and circuitry I could find. In the end I not only learned how to completely wire in the RB, but learned how most of the electrical sensors work and how to troubleshoot a lot of electrical problems.

This is what we want you guys to do. This forum shouldn't be the idiots guide to RB swaps, even though that is what it's becoming and the reason I don't come on here very often.

NOW, if you've done your own research and wiring and have a specific question because something is not right, we would be more than willing to help you out. That is what this forum is for.

I agree that u don't want just anyone with a little money doing this swap without giving the project its respect and doing th research. I have been researching for a little more then a year and i'll be starting my wiring in a week or so and i have both FSM and all the info i could find online and I just like to go over everything I do and make sure its right. I have a rough draft of my own guide on paper for myself and I want to make sure NOT_A_KA's guide is correct so i could have one more confirmation of my own guide. But if you think about it the people that just pay to have their harnesses made for them are the people that aren't giving the prject its due respect. I mean i know alot of ppl have the knowledge but not the time, but anyone with the money can get it done and just plug it in. So I think its better (in a way) that ppl atleast attempt their own, dont you?

[Bluefire]

Money and respect have nothing to do with this. I could care less if some super rich ricer wanted to do this or some broke *** drifter. If someone wants their harness made by somebody else, thats fine also. Whether it be time, money, knowledge, or just laziness, at least they know what they want and are getting it done.

What I am trying to say is that if you decide on undertaking this swap yourself, you are much better off now and in the long run by researching the info yourself. I can tell you how to wire everything and exactly what to do to get this car running, but will you learn anything? Sure but not that much. But when you do it yourself and make mistakes, you start to learn about the car. You learn by having to troubleshoot, and figure what went wrong. It might take a day, a week, or even month going over the fuel pump, injectors, coilpacks, ecu, maf, timing, etc etc... but everytime you go over things like that, your learning something about the components and how they work.

Here is my advice. Do the wiring to the best of your abilities. If somethings not working go over your wiring again and look for any mistakes you might have made. If somethings still not right go over it again until you can't come up with any new ideas. Then come here or even email me or one of the other guys. Let us know what is working, what isn't working and exactly what you have done so far. Then we'll throw out some of our ideas of what you can do to fix the problem.

Think of it this way. If you go to a mechanic for some help, which question do you think he'll be more responsive to: How do I wire in an RB motor into my 240sx? or I'm trying to wire my RB into my 240. I've got power and spark but i'm not getting any fuel. What do you think I should check?See the Difference?

Anyways... let's end this discussion. 1. Don't follow Not_a_ka's guide there are a lot of mistakes(But he's moving in the right direction). 2. make a check list of what needs to get wired up. 3. Mark the ones you are absolutely sure of and marks ones that might be wrong. 4. Wire it up. 5. if you've got a few question on some specific things you can't figure out email me at srhim214@gmail or PM some of the other guys

That is completely rediculous. Who cares about how is spending the money or who wants to do the wiring from scratch. And what are you talking about giving the respect the swap deserves. All it is, is an engine swap. A lot of people, myself included, don't have the time or know how to do the wiring. That's why a guide like this would be helpful. If there is something wrong with his writeup give some input instead of telling them to figure it out themselves because obviously he tried and it is wrong.

I've learned all I want to know about cars and just need to get this thing done as quick as possible, so any corrections you could make would be great.

NO one here is going to baby you and tell you exactly what to do, if you're looking for that then good luck. IF you don't have the time for this or that then don't do the swap. Simple as that. People who don't have the money or time or another car should do some research before even contemplating this swap.

[ehacker01]

I don't need someone to hold my hand while I do it. Al I am saying is instead of saying "no you're wrong". It would be more helpful to everyone if they would just say what is off. I have the time but it could be much better placed elsewhere. I know what has to be done but this guy is trying to save all future swappers some time.

You sir are the exact reason we don't put out entire guides to swaps. If you don't have time, don't know how to do wiring, and don't have money to pay someone else to do it. Well my friend you are SOL. And if by some miracle you get it running. I hope you have fun figuring out all the little problems on your own.

For anyone actually willing to learn you can PM me your specific questions and I will help you out

OK everyone needs to relax a little.

1) NOT_A_KA i removed your pinout "guides" because they are incorrect. i dont want you to be responsible if someone wires something incorrectly and causes electrical damage. for future refrence when people say you have wired things wrong please remove the spreadsheet yourself.

2) this topic needs to stay on topic, the topic isnt weather there SHOULD be wiring guides for the swap, that can be another thread if you guys would like to discuss it. this is about trying to wire s14-rb25's.

my .02 is part of the mistique of a RB25 swap is there are no guides like this. you eithre paid someone to wire it, or figured it out yourself.

[ehacker01]

I am confused as to what is wrong with the guide. I double checked with my notes and with the rb20det->s14 swap and it is mostly correct. I am only doubting a couple of RB25 pins:

191246

and #11 should go to KA #15? for power steering idle up?

Am I missing something that is wrong because the rest of the necessities look correct.

I am also wondering if I can just run the wipers, ascd, and rear defogger from my ka harness in parrallel with the rest of the RB harness.

[300Plus]

yeah we dont need people like that. And for the record I think anyone who has takin the time to do the swap themselve and who has done enough research to get them this far then they've earned it. And I think a small guide like this would help a lot of people out. so i guess what it comes down to is if those who agree would help fix the problems with the guide then that would be great

[Wulfgang]

Some of you guys must have forgotten what it was like before RB swaps became so popular. We shared information with each other so that we could save ourselves time and money. These newer people are no different... except they are starting later than some of us. I agree that people should search well, then search well again before asking noob questions, but I also know that no reliable RB25 wiring guide has yet surfaced on this forum (which should be the internet's most complete source of RB25 -> 240SX information). Some of you guys are being extremely protective of what's not even yours.

And people have different areas of expertise. For example, who here made their own engine mounts??? Anyone??? So if you didn't make your own mount and you didn't use the Skyline x-member, then you probably bought one from someone else WHO ALREADY FIGURED IT OUT FOR YOU. No expertise in machine work or welding, right? Likewise, some of these guys have little expertise in wiring and they'd like some help. So please give it. I do not want to see this great forum turn into Freshalloy because of unhelpful attitudes.

Having said that, I need to say something on topic as Kamin requested. First, I would like to see a real, decent wiring diagram for the RB25. I would settle for an F3 pinout, but I'd really like to see the real deal, like the R32 engine manual on pdf. If someone gets that for me, then I'll make a guide for the S14 in my spare time. I may step up to an RB25 someday, and I will have more confidence in the wiring if I figure it out myself (but I may still buy mounts from someone else since welding is not my area of expertise!!!). May take a little time, tho.

[Joe]

ok any more of topic discussion and this thread gets cleaned up.

last warning.

[300Plus]

Glad to hear we go some support. So lets do it! I have both fsm and all little guides (like how to wire the r33 cluster) but nothing for the f3 and m63 I have spent hours going over the FSM looking for pinouts since I'm not the best a reading schmatics just to finout they never included a pinout guide in either FSM. If someone with the knowledge could step up to the plate and make a F3 M63 wiring guide I'd be happy or a all out wiring guide. (my only grey area is the F3 plug) If I can help with resources pictures let me know!

[eh?]

Everything you need is available on my site including the best possible RB25 wire diagram (not a schematic)http://www.rb25det.org/RB/rb25diagram.jpg and an M63 pinout is linked. I spend money to host these files, the very least someone can do is try to look at them and learn.

[stiergott]

i spent about 1 hr in the garage with a voltmeter and the clip and got pretty much everything i need, accept the sensor thing and i got that wrong cause i used the wrong pin on the ka harness. they are right that pinout was way off, i mean you had **** runnin into datalink wires. it doesnt take that long and you can get the car running using just the engine harness as a guide. as for there being a guide, who cares? there is an sr swap guide and people still manage to **** that up.

[NOT_A_KA]

Your site does have the best information available. Using your site and the FSMs, I put together that excel sheet to see what I might of done wrong in my wiring. For people that still have that excel sheet compair this diagram to the RB F3 pinout contained in it. I think you'll find them the same.

ehacker01I think your right about 11 going to 15. I am running the rear defogger parallel and took out the cruise control. You can run the wiper stuff parallel but It should also work through the f3 plug.

[300Plus]

keep us posted on it NOT_A_KA, oh and check your email

[ehacker01]

I tried reading that guide to write a pinout for the rb f3 plug but can barely read it. do you have a clearer copy of it?

[NOT_A_KA]

Open it in Windows Paint (Assuming your using windows) Goto page setup and select "Fit To: 3 by 3 page(s)". Then print it out. You will have to peice them together but you will be able to read it.

[300Plus]

So if he revises his pinouts can he repost?

[Joe]

absolutley! if its correct ill gladly post it and add it to the guides. after its verified. we do not want wrong info out there. ill verify myself too.

[Spazz]

Wulfgang, i have all the r32, r33, r34 manuals on .pdfmy aim is zexthar and im more than willing to share this info with fellow niconauts.

Spazz.

[Wulfgang]

Spazz, check your email.

[ehacker01]

last night I redid not_a_ka's f3/m63 pinout for the RB25det and came out with the exact same thing. I could really use some input as to what is wrong with it. I'll be starting my wiring this week.

[300Plus]

post it up here and stat that it is only for evaluation purposes. then once we get a few ppl to review it we're in good shape. I'll be doing my wiring in a week or so and I'll go over the guide and let ya know if it worked for me.

[ehacker01]

Here is the f3/m63 pinout for evaluation purposes only. It almost exactly matches not_a_ka's. The wiper stuff was taken from not_a_ka's pinout. I also gave the corresponding names with the colors from the rb25det, de diagram that was used from rb25det.org.

I will be trying it this week as well and will give updates.

[300Plus]

K this is one side of the of the plug...literally haha can we get a few reviews on this pinout
