Any help would be appreciated! I have a 1985 Mustang GT that I have rebuilt from the ground up, but recently I decided to change out the original gauge cluster and put in a cluster that had a 140 mph speedometer. the replacement cluster was in excellent condition but it was out of a 1984 turbo coup. There is a turbo gauge in place of the ammeter, and the printed circuit looks identical to the one I took out. However, I have no lights in the cluster even after putting in all new bulbs. Has anyone ever done a switch like this? Can anyone give me the pin wire identification from both of the plugs that go into the back of the cluster.
Thanks, and have a great summer.
Thanks indy 2000. I got this piece on line so I don't know if there is a diagram of the pin location. (84 Mustang turbo) I haven't found one on line. I checked the pins last night with my meter and found 12+ volts in several locations but it's not easy getting under the dash to trace the wires even with the driver's side seat out, but thanks for your response.
