1989 Cadillac Brougham V8 Two Wheel Drive Automatic 66000 miles
I have a 1989 Cadillac Brougham, and it wasn't driven very often for about three years. I just had a tune-up done, and the check engine light is still on there. I work at a Chrysler dealership, and the mechanic has a GM connector to see where the problem might be. He wasn't sure if the Cadillac had a connector like they use (he said he knows that at least in 1994 they used what they use now.) Short of spending alot of money for his diagnostic fee, is there a connector that could work?
