i have a obd1 ls in my hatch now and just got and obd2 gsr what do i have to do to get it to work. ive been reading and seen people useing the obd2 harness? so if someone can post a better link that i cant seem to find or tell me what to do gonna try and get the swap done this weekend and ecu im using is obd1 p72

 

Is your eg wired for vtec already. I just did this swap in my 94 vx. Very easy. I used a obd2 GSR harness and only had to wire knock sensor from shock tower to ecu. Search google for ultimate GSR swap in eg and you should find the link. On my phone otherwise I could give you the link

If your using the stock IM than you will have to wire up the secondary butterflies and knock sensor.
