I recently purchased a tailgate LED bar with reverse. I have everything hooked up except for wire that controls reverse. When I take rear light out how do I determine which wire I tap into?

Have someone sit in the truck with it in reverse then test the wire. If you don't have anyone. I didn't have any available at the time so I put my key in the on postion without starting the truck and put the emergency brake on. Then I put it in reverse and tested the wires.

I used the exact method for all my reverse lighting endeavors.
And believe it or not....if you use a lil common sense and take the proper safety precautions...the objective can be accomplished with out any kids or dogs being ran over.
Who'd 'a thunk it.![]()
As long as the truck isn't running there isn't to much to worry about.
8 speed transmission will automatically go to Park if you turn the truck off, just fyi. lol
