I am not sure what you are talking about, but I think we can get you fixed up. first do the lights you are trying to put on have instructions if so can you please upload them? Next here are the headlight wiring diagrams for your truck so we can see what is power and ground.

Check out the diagrams (below).

Please let us know.

Cheers, Ken
