Ok first off I've searched my a$$ off trying to find some direct info on this, but have come up empty handed. Im about to do a OBD1 GSR Swap into my OBD2 ek hatch. My question is what all is included in the OBD conversion besides the harness? I have the entire swap, since I bought a wrecked 95 Integra GSR (in the rear)....Please help me so the winter project can begin.

 

Nobody?

 

just use your harness in the civic and make or buy a subharness to connect all the sensors from the GSR that are needed (VTEC solenoid, VTEC pressure switch, Knock sensor, IAB, convert your 3 wire IACV to two wire). You'll also need to swap over the plugs from the GSR injectors to your harness and do the same with the distributor plugs to be able to use the GSR's injectors and distributor

OK so basically just buy a subharness (from you (lol) for all the vtec stuff, and than just swap over the injector clips to the civic harness, as well as the distributor plug. Correct? Than do i run a OBD2 to OBD1 jumper harness to the ECU and use the GSR ECU? If so than i just buy a conversion harness for a 96-98 (mines a 97)..CORRECT? Or did I miss something?

Yes use the GSR ECU. Use an OBD2 to OBD1 ECU adaptor. You'll have to swap over plugs on the alternator too as they are different between OBD1 and 2.
