I'm having issues with my trailer running/tail lights. Ive checked all the fuses (i think) the white with brown stripe wire is intact from the fuse box to the back of the truck just no power. I popped the headlight switch assembly but I'm having a hard time understanding what each wire does and reading electrical diagrams is not my strong suit. Below I found this picture of the wires that go into the switch assembly. Thanks in advance

Do you have the factory trailer plug in back. Usually, the tail lights are the brown wire. White is ground. With the headlights on, use a volt meter to check the plug in back. I don't remember which terminal on the 7 prong with relate to the tail lights.

I am having the same problem. The break lights and turn signal work but running lights do not work. I have also checked all the fuses all good. There is no power to the factory plu.
