My truck has an universal ignition two prong switch and I want to change back to the original. The original has three has three. What wires go to the original three prong switch?

The stock switch may have three terminals, but the factory wiring diagram shows only two of them being used. If you have added accessories such as a radio or heater which you want to be controlled by the ignition switch, it is possible that those might be connected to the third terminal.


Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.
