Look under the rear of the truck for a trailer light harness .Look it over real good as many light problems start there.

Have you checked all of the grounds, headlights too.
Redo all the grounding in the headlight area.

Sometimes when a ground goes back in one component, that component will attempt to locate and use another components ground via the actual component causing the second component to activate a little.
