I have a 95 civic which is obd1 and i want to swap b18b from a 99 or up integra. I think its obd2b or obd2a im not sure.. So do i use everything from obd2 (ecu, harness, distributor,ETC) to swap the engine? Also do i just have to swap the engine harness or the whole car harness? if thats the harnesss i need to use, will the rest of my obd1 harness plug in to obd2 ecu? I did a search and read the stickies but all it said was search or it didnt have my specific problem... Thanks guys
