The 8 wires behind the glove box, I spliced the two wires together needed to power the AUX1 switch. I then ran the red wire coming out of the light bar to the same pass through wire in the engine bay located right behind the battery. (The other end of that same wire was one of the two wires I spliced together behind glove box). That's all I did. And of course grounded the black wire. The only wiring work on the inside of the cab was splicing the 2 appropriate wires together to provide power to AUX1
Sounds like a good install. Have you tried changing the fuse to see if the results are the same?
