So I've been looking around for an answer to this question and haven't really got a definitive one: I have a USDM 2002 WRX and was wondering if I can use the USDM harness with the JDM ECU and engine with the additional iWire wiring kit for AVCS. Will this work or will I need an AVCS harness? Thanks!

If you're talking about the USDM bulkhead harness, then yes. You need the JDM engine harness and then either buy a wiring kit or make your own.

I used a JDM engine harness and then ordered a jdm body harness separately. I cut all the wires off the body harness except the ones for avcs and ran it through the firewall. Itís only like 8 wires you need I canít remember exactly.

Correct, use the ECU and order the AVCS wiring kit, and make sure you change the required pins in the other harnesses
