So I found an ECM in a car bought it watched it run no MILL lights, and I put it into my car and the MIL light comes on still? Can someone who has a 5sp 91 integra take a picture of their wiring harness so that I can see if mine is maybe missing the wire for the baro switch. The following sentence is speculation. Maybe the car is supposes to be wired for the BARO sensor to recieve information, and that wire is missing on my harness? I think that maybe the wire that should be there is missing. So I need pictures that are highly desriptive so I can compare to mine. That way I know if there is supposed to be a wire goignt o the pin on the ecu
