Looking for info on switching out idiot light cluster to rally gauges on a 72 lemans ; i know i have to change the oil pressure and temp sensor on the engine ; but i believe there is a wire or two that has to be swapped in places on the (12) prong plug that attatches to the cluster ; any ideas ; thanks ..
Upgrade to 72 rally gauges ?

do you have the 1972 Pontiac Shop Manual, the wiring diagrams are in the back of the book and that would be your best resource. There may be a different dash harness and the book would indicate that. The 1971 book that I have shows nothing different as far as the harness on the back of the board.
