I droped a 96-98 jdm b16a2 into my civic. At the time I was running an obd2 to obd1 conversion harness but now due emissions I must switch it back to obd2. I wasn't sure which ecu's I can use. Does it matter if I use a USDM ecu or do I have to use JDM. I know it needs to be obd2 but wasnt sure about the rest. And is it the same for the wiring harness?
