I'm looking into swapping in a JDM GSR into my 96 hatchback (CX). Only problem i'm having is that i'm unsure on what to do with the GSR harness and my single cam harness (Non-Vtec). I've done some research and have found out that I have to use my single cam harness in order to make it work. I have a P28 ECU laying around that I would like to use, along with the OBD2A-OBD1 jumper harness. Can someone please give me some help/info on where exactly to start? Any plugs I would have to change? Extend? Any info would be greatly appreciated. Thanks in advance.

 

Look into the FAQs. This is covered. What year gsr

why would you want to use a p28 on a gsr motor? unless it chip for the motor you intend to swap in i wouldn't do it.

Check out my thread it should answer most of your questions, but in a nut shell you'll need:
-use your harness
-wire in VTEC
-convert your 3 wire IACV to 2 wire
-using the p28 you won't need to extend the 2nd 02 or wire up knock or IABs

It won't be necessary to extend any sensors then?
