Spun a bearing, bought a new motor w/ ECU, was supposed to be OBD2B but was OBD2A. The harness that came on the motor is JDM so it won't fit properly in my engine bay. Should I use my harness (obd2b), the JDM ECU (obd2a), JDM motor, and a Boomslang OBD2B -> OBD2A conversion harness? It looks like there are 3-4 plugs that my harness has that the JDM engine lacks sensors for. Crank sensor, VTEC solenoid (mine had 2, JDM has 1), one on the IM, and one emissions/fuel (black canister). Anything else that would need to be swapped out/rewired? What do I do with the unused plugs in the harness?
