Help !!!!!
Hello everyone, I`m in need of help, I have a 1989 Corvette coupe, my service engine light is on, but I can`t find the ALDC diagnostic connector. could someone please tell me where it is. I know nomally it on the underside of the dash on most GM vehicles, but don`t seem to find it there on mine. Also on the left hand side, under the dash, there is a black box with a group wires, and a couple of relays going to it. Is this the powertrain module ? If anyone can help, it would be greatly appreciated. Thanks, Bill.
