So i changed the deck in my truck the other day. I know it worked because it was in my parts truck and i had it set up in my shed as well, i went to put it in my rig and now it doesnt work, my highbeams dont work and my interior lights dont work. WTF?!

 

Check fuses.

 

 

nope that's it. Don't take for granted they are good, swap them out with known good ones.

 

alrighty i will check them again, thanks dude.

 

Both systems highbeams and in cab are on two separate fuses as well. Radio/Dash and Dome I believe are on the same fuse, but not 100% on that without looking at a fuse box top. Yours is a different year as mine, so looking at mine isn't gonna help.

The headlights fuse should only be under the hood. Dash lights/radio etc are in the kick panel. I don't think the kick panel feeds the power to under the hood to trip the headlight relays. But there is that possibility. Without looking at the wiring diagram I can't say for sure.
