I have a 1990 civic hatchback. I have a D16Y7 engine, a P06 ECU with MPFI/OBD1. I need a new wire harness because there is a short somewhere from the guy before me. So I found a new harness on ebay but I have some concerns. The ones I see on ebay are automatic and OBD2A. I was going to get a OBD2A to obd1 adapter for my ECU but I don't know what to do about the automatic. I can't find a manual to save my life. How would I or is it possible to convert the auto harness?
