theres only 2 wires at the reverse bulb, one is ground the other is 12V switched reverse. or you can grab it at the 7 spade harness. since im assuming your doing a camera you will need to run the wire to the camera any way. most of the other places in the cab it will be in the form of a data signal, you can get it at the BCM, though the wire color escapes me or MAYBE in the drivers kick or fuse box.

if you are replacing the radio with a touchscreen to run a camera, most of the retention harnesses will give you a + reverse output as well as - parking brake, illumination, VSS and mute. though without a retention harness you will not be able to get the wires behind the radio since they are running on high speed can and not analog +-
