did search already.. can anyone help me?

 

You most likely won't find the whole ECU wiring diagram online. In the ESM I don't think they lay it out as a whole harness. You would be better off asking for specific wire functions. I'm almost positive that in the ESM every thing is laid out by function and idividual systems, not entire harnesses.

What are you looking for and what are you trying to do?

 

Try this.

just trying to hook up apexi rsm.. got this diagram from 350z forum.. is this close to what i'm looking for? thx for the link hooner.

 

I would say that that was a good starting point. Wire colors change frequently but pin locations seldomly change. Just make sure to test and verify all wires before hooking up to them - the knock sensor might be hard though!
