3rd Gen Rear Bumper Flush Mount LED's - Power Source?

Does anyone have experience wiring in rear bumper flush LED's.
I have them installed on aftermarket bumper, but I am not quite sure where to grab power from. I would like to have them work with the rear cab light/switch from inside the truck I think/as well as when in reverse.. has anyone tapped into this, or know which wires in the rear tail lights are power? I could tap into that line for the reverse function.

Thanks in advance!

 

you might be able to tap into one of the wires from the trailer plug assuming you have it. If not im sure the tail lights will work for the reverse function you are looking for.

 

You need this, or some version of it.

if your truck has the factory trailer plug, i highly recommend buying a harness like this to gain access to the stop/tail/turn/reverse/power-when-on wiring already at the rear of the truck.

the main benefit is that it's plug-n-play, and it's a sacrificial connection that, if you ever run into any issue with your modifications at all, you can simply disconnect the harness, and get home safely from anywhere.

 

Get a harness specifically for that. Run power from the battery. Best bet.
