    I am trying to hook up reverse lights on my back rack. I know this has been covered before. Where is the best place to tie into the factory reverse light wire. I have a 2002 Chevy 2500 HD. Do you find the trailer wires that run under the bed? Do you find it right out of the fuse box? Any help please. Thanks in advance. Any pics or diagrams would be great...

    I think the actual switch is on the tranny, but I am not sure. Others may have more experience to confirm. I believe the reverse light wire is light green. You could follow the harness from the back of the truck to the transmission and tap in there. After saying all that - if it were me, I would wire the lights to a switch on the dash. That way you can leave them on all the time when you are plowing. It is really nice to have light behind you all the time. I think I can plow faster this way too. Plus you don't have to worry about overloading the reverse switch or curcuit.

    Under brake master cyl group of wires with snap connections. thin green wire is reverse. do a search on install with 3 way switch and a relay. you can turn lights off, on, or w/reverse.
    Or, trailer harness if you have the round plug style. Center pin should be reverse.
