Topic: Install 3rd Brake Light/Problem with running lights (Read 858 times) previous topic - next topic

I have installed a third brake/turn light up high on the rear if my 2020 Unity
I taped into the wiring just before the trailer plug.  Everything works except the running light. Lights work
on the Unity but no power to the running light wire to the hitch plug. Checked fuses under drivers seat 10 thru 15 and all tested good.
Universal wiring guide shows the brown wire should be for running lights. Is LTV different?
Any ideas?
Thanks
