This is my first swap, and in need to help!! I have a b18a1 out of a 92 integra. I put it in into my 89 crx si. I would like to run it obd0 because I dont want to have to buy the ecu jumper harness. I believe the 92 integra motor is obd1. I don't have my stock harness from the d series. So i bought a harness from a 90 integra, because i hear it's plug and play. But when i was plugging everything in today, i noticed that the plugs coming from the body, either don't match the plugs on the harness, or dont' have a plug at all. Do I have to cut any wires and plugs?? Also i believe I need to take off the injectors from the obd1 and put them on the obd0, true?? I guess my main concern are the plugs coming off the body that dont have a plugs, or plugs dont match on the wiring harness from 90 integra harness. I'm confused , i need help from the experts on here.
