Setting up my piggy back system

[s13drft89]

Hello,i had posted up for help on putting in my apexi safc, well some people had given me the diagram on how to hook it up, and well it does not match up to my ecu harness, it matches up to the sr20det harness. On the ignition wire(red) it shows it to hook up on the right second to first wire, well that one is a ground, and the third one is the ignition wire, on my ecu. Iam not sure about the other wire such as throttle air flow etc.. is there anyway someone can post a picture of the wires they hooked it up as,meaning taking a picture of the ecu with the wires hooked up, please anyone help I have a 1993 240sx dohc and the apexi safc is the version 1

safc 1 or safc 2?

If safc 2, you can go to apexi site, d/l their diagram thingy - should be world diagram n3b - or something like that... haha, it's late at nite & I have an sohc but should be similar - I know there is a thread floating around somewhere w/ safc 2 instructions... safc 1 good luck .

you're going to have to use the Apexi wiring instructions in conjunction with your ECU Pinout Diagram (as listed in that thread)

The black and brown ground wires have to be connected to the SAME ground wire on the ECU, soldered 1" apart.

on SAFC wiring harness

Red = power Green = TachGrey = Throttle Position SensorBlack/Brown = GroundYellow = Maf output TO ECUWhite = Maf input FROM MAF

on Car wiring harness

Power = Black/White wire pin # 38 or 47Tach = Yellow/Red pin #2 TPS = White wire pin # 20Ground = Black wire Pin # 39MAF = White wire Pin #16 (this is the ONLY one you'll have to cut)
