Hey whatsup guys i gotta B18C with the JDM engine harness on it, it's going into my 93 si hatch. I got the single vtec harness off the Z6. The swap is OBD2 and my car is OBD1.

My question is what are the pros and cons of using the old wiring harness vs using the JDM harness and cutting and extending wires. I've heard of both, ive also heard of using a USDM obd2 gsr harness..whats the easiest/most efficient choice here?

I'm not too good when it comes to this part any help is appreciated..also if anyone knows where to pin the knock sensor that would be

thanks in advance

 

Easiest thing is to get a '96 - '99 5 speed Integra harness, any of them will do. If it's from an RS/LS/GS you'll need to add the wiring for vtec and knock as well as the IABs. Do not try to use the RHD harness, just keep it from connectors (you can salvage the vtec wiring from it)
