This is caused by the dimmer switch being out, here is the headlight high beam wiring diagrams so you can see how the system works and I have included how to change the dimmer switch out in the images below. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Yep, was there an aftermarket alarm on this truck? I see open wiring? To look to where this can connect back up. Also, can I get a better shoot of the wiring from the connector?
