Alright guys, gonna need a lil help on this one. Just deloomed my complete engine harness and I'm ready to start eliminating circuits I don't need. Only thing is the diagrams I've been looking at don't really break down particular colors and pinouts. Maybe I'm reading them wrong? I've done plenty of efi conversions on Hondas so I feel like I can handle this. Anyways what diagrams are you sr guys using?? Help me!!!! Haha

No pinouts for the S14 SR20DE engine harness exist that I could ever find-- so we made our own!
Send me an e-mail to
sprisomotorsports@gmail.com and I will e-mail you a pinout.

I have the 200SX/S14 electronic Manual which has the ECU pin outs.
It is a .pdf file 27.8Mb small

If anyone would like a copy, see: -

I think you will find that 200SX manual only has the SR20DET wiring diagram-- NOT the SR20DE version (and the harnesses are different!)

I wouldn't be surprised, but it is there if anyone wants to study it.

Ahhh... gotcha. I was assuming Normally Aspirated.
I should have both versions of the S14 SR20DET pinouts-- let me see what I can dig up.

Although I understand you want to wire your own, I used these guys. We unrolled it from the box, layer it out on the motor, went click click click, and fired the motor.. And assuming you are running stock motor with that NA computer, you click the options, and I think they have it on the shelf ready to ship

If it's a stock motor/stock computer, he usually has them on the shelf.. If he has to match a custom computer to a custom frankenstein engine, it takes a couple days once yours gets to the top of the list. If you need something custom, call him as early as possible and give a target date. But for stock/stock, just make a call and check if its on the shelf..
PS: When calling, check the Formula Drift schedule. If there is an event, he will probably be there since multiple cars run his harnesses, and can be tough to get ahold of that weekend. But he will call you back..
