Isuzu Repair: 1994 honda passport, honda passport, autozone


Question
My engine check light comes and goes. I think I located the OBD1 connector next to the ECU it has three leads a black, red(center lead) and yellow which two do you short to get the dash readings?  
I also located a connector in the engine area that looks like it can be a OBD1 connector a green connector with three leads gray/blue, gray/red (center lead)and gray/black is this the OBD1 or some other connector?

Answer
Well first of all Joe skip all of than nonsense. Have you tried to clear your computer by unhooking your battery for thirty seconds and then reconnecting? If that fails go to Autozone and they scan and read codes for free okay? They will tell you what is wrong and what needs to be fixed.
