Need some advise on checking the gauges and wiring connector in my 72. Fuel gauge is the only one working, PO installed aftermarket oil and temp gauges below the dash. I would like to get the originals working. I have the cluster out, just need to know how to check things out. thanks

OK, first off you need to know if the truck came with the factory gauges are did he add them. If he added the factory gauge cluster the wiring bulk head is not right for the gauges. The wires in the connector aren't in the same spot for the gauges. You can swap them around and get them right but some one else will have to say which ones you need to move.

The circuit board needs to be for the gauges also and in good shape to start with no tears. As for the oil gauge it's mechanical it needs the tube coming from the motor ran to it.
