Whoa whoa whoa, hold on a sec here guys. '96+ Integra use the same harness as '94-'95 Integras, but with some extra wires on a seperate plug for the OBD II related sensors. If you have the swap in your garage, you should be able to compare the wiring harness on the engine (assuming it hasnt' been cut) to the wiring harness in yoru car. You'll notice they're very similar. Now I haven't done this swap myself (OBD II USDM Integra into EG civic) but from what I understand, you can just take the harness on the engine, plug in everything fits and find yourself and OBD I ECU (P75 is the non-VTEC DOHC Integra one, I think you need a manual version or you'll get CEL's) and your all set. Like I said, I haven't done that myself, my swap was an OBD I engine into OBD I car but I've heard from a lot of people that it is true. Compare the harnesses and see what you think.
