    I installed some (2) aux back up lights today for plowing,I taped into the back-up light wire for the trailer plug like I have on my previous trucks.I thought all was fine till I was backing in the garage and noticed the lights flickering and then they Quit.I put the truck in park and then back to reveres and just a flash.Checked all conections and seemed fine.I finally just clipped the wires and factory lights were back to normal?While the factory lights were on I went under and touched the wires for the aux lights back to were I clipped them from and they would stay! WTH!!! I'm at a loss! If I had a trailer with back up lights Am I going to lose my back up lights as well! Thanks to all!

    Did you use a relay with Aux power or just tap into the reverse circuit. It could either be overloading the circuit if you aren't using a relay or a bad relay if you are.

    I tapped into the reverse light wire at the trailer 7 way plug.Thats why I am at a loss.What would be the difference if I had been pulling a trailer that had back up lights? DC already wired it for that but it Won't handle it! Thats B.S. if that is the case!

    You need a relay. I did the same thing and needed a relay.

    I dunno about the trailer wiring but install a relay and see how it works for you.
