Okay here is the story, I have a 96' delsol si that I put a 96' jdm gsr engine into. I used the engine wiring harness from the del sol for the gsr. I recently totaled my del sol. Now I am getting an EG hatch. I put my old D16y8 back into the delsol. If i put the wiring harness back on the delsol will I be able to use the wiring harness from the 92-95 hatch with the GSR? I alerady have an obd2 to obd1 conversion harness that I was using because I am running hondata. I bought the 96 GSR because my delsol was a 96' and they recommended buying an obd2 engine for an obd2 car. Now I have a fully built obd2 engine but I want to put it in an obd1 car. What other sensors are on obd2 vehicles (besides the second O2 sensor) that I would be missing? Also would an OBD2 harness plug into the connectors in the engine bay on an obd1 car? I am trying to get a vx or si hatch that are already wired for vtec. Thanks for any help that is given.
