    I have a 2011 Silverado 1500 and I would like to set up some back up lights to come on when the truck is in reverse via a relay. I need to know which wire in the harness to hook to the relay to trigger it. Does anyone know which wire to use????

    Do you mean on the tail lights or the trailer plug?

    On a 7 way trailer plug, reverse should be the center pin.
