So just bought a jdm H23A dohc vtec blue top. The motor is obd2, my car is obd1.... i have a tuned ecu for the H23A, but it is obd1, the H23A engine wiring harness is obd2 and wont fit my tuned ecu, i know u can buy a jumper adapter, but the import engine has 4 connectors, 1 of which is cut off, ive seen in other videos with these import engines that this is normal. Anyone else who has done this swap have any ideas or input fkr me? Thanks
