Well my backup lights dont work ether.Mine is the neutral start switch on the automatic tranny but if you have a manual tranny then there should be a plug looking thing with a wire running to it.On an auto transmission it is on the driverside on the manual trans dont
know which side.but look for wires you, should find something around there that may look like a plug type switch. hope this helps..,
