I've attached a diagram of the ECU pinouts for a UK 200sx S14a SR20DET.
Jez, does this version look correct and match the one you used to make your wiring harness?
Cheers
Dan

Looks ok to me - probably worth double checking in the service manual. I used an S14 loom on my engine, so the pin outs are a little different - I've passed on my wiring to Ryan

But making looms is so therapeutically satisfying...

LOL
I actually meant wiring diagram - not the actual wiring

Nearly finished your Loom Dan
Need to know though abit more abit the ECCS Stuff and how the ecu power is switched on
Also can you get the exact pin descriptions of what each CAS pin does. Ie which is ground, which is signal etc

Here's a link to the S14a Service Manual supplement

Hope it has the right info in there, otherwise I'll try and get the info from the club.

Looking at Page EC-23
Pins 31 and 40 are Camshaft position sensor Reference,
Pins 22 and 30 are Camshaft position sensor Position
Page EC-132 onwards has the full list of ECU pin outs....wish I'd seen that first!

How's it going Ryan, did you find the info you needed?
Started pulling the old bits out of the car this evening. AVCR, SAFC2, EDFC, Racelogic etc....amazing how much extra wiring I seem to have accumulated over the years. Even found parts of an old carphone kit still tucked behind the dash from years ago! Think I have buyers for all the old bits too which should help towards some more suitable suspension.
Charlie said you use a Mac valve for the boost control, so I'll need to get hold of one of those too, plus a different filter kit to replace the airflow meter and current apexi filter. The intercooler cold pipe will be coming off this week so I can take it to get a boss welded in for the intake sensor
