I got it fixed. This was a nightmare. Back in August I had an aftermarket DVD player installed in my truck. The gadget worked fine and I didn't notice any problems. Well, last night I installed my cab lights. Routine installation except that I had to R&R the aftermarket DVD player. Today I notice my cargo light won't go off and my brake lights aren't working... uh oh! So I tear things apart and find that I'd run a screw right through the wiring that runs on top of the headliner. Looking closely I saw that the screw had been through these wires since the DVD was installed. I just happened to actually short things. So I had to repair all those wires on top of the headliner and replace the blown fuses. Nightmare's over and at least now I know my truck won't crap out or catch on fire one day due to the crappy DVD installation.
