I have no idea where this plug goes, I know that I had the black and red wire plugged into my f3 connector at the black and red and the car had started for a couple of days...but its not starting anymore and im trying to figure out what these wires on this plug do?





it comes off the main engine harness somewhere? dunno what it used to be connected to.

is that the plug that's around the area where the O2,Maf and boost solenoid are. If it is you need the gray wire to power the injectors.

thats what it looks like to me... i think its what connects the interior/engine harness to the engine bay area harness in the skyline... but yeah you do need the grey wire to be cut and connected to a 12v to power the injectors

Well i noticed the bigger thicker gauge red wires on it and have already tapped that injector wire somewhere else? Anyhow my injectors are getting 12 volts, I just can't get any spark =T
