Re: 72 starter wiring under dash help
Is the car automatic or manual. Or was it converted over to a manual. That connector with the purple wires should connect to a half moon type of switch on top of the column down near the firewall. There should also be another connector hooked to that switch that controls the back up lights. If the car was converted to a manual you can run a jumper wire between the 2 purple wires to get the car to start but you will have to dump the clutch when you start it because if it's in gear the car is going to jump. As far as the back up lights working if it was converted to a manual you would have to run a switch off the 4 speed reverse linkage and run the wires up to the other connector on the switch on top of the column.
