Guys my uncle gave me a wiring harness and say that it was off a prelude motor he had a while back . How can I tell what OBD 1 , 2a or 2b. It has grey plugs. It is only the engine harness no computer harness ends is on it . help guys.
If it has 2 O2 sensor plugs it is OBD2a or b...best way to check. The OBD1 only had 1 O2 sensor plug You wont be able to use that harness without a LOT of wiring. It probably came from a jdm engine...the tend to cut motors out of cars once they fail inspection or some shit.
yeah, if the ecu end is cut.... its pretty much worthless. you inherited yourself a couple hundred feet of spare wire IMO
