Because alot of the electrical is aftermarket, all the wires are there, but in different places than any diagram will show. I have the guy I bought it from to thank for that, haha. The wire was placed just out of reach and sight near the headlight switch.

Well, I found the problem, and fixed it. Turns out it was a cut wire where they all intersected, almost looks like a mouse chewed through it. I would not have found it without the help of you guys tellin me to tear apart the inside of my truck, haha. As always, much appreciated. You'd never know how much a cab light can be taken for granted until you don't have one.

I'll check that, it's a pain to get to though. You were dead on, there was a grounding cable there. Took a minute to find it. Unfortunately, the ground makes good contact and I traced the wire, it's in good shape. There was one fuse port that didn't receive any voltage, but it was the instrument cluster, and strangely enough, they still work just fine. How it's still working is beyond me. This helped quite a bit, I was bent over backwards today finding wires I had no idea where the hell they went, but the diagrams on that pdf told me exactly what they were. I do think I have narrowed it down to the battery connection, however. All grounding looks good, but none of the wires are receiving voltage.

Pretty much the worse thing I could have been doing right before an electrical issue: nothing. It worked, I shut it down, and the next day it didn't work. I did nothing differently that day than any other.

I'll try to make this quick. I have an 88 with interior electrical problems. These components don't work: Cab lights, 12v outlets, radio, cb radio. Because they all failed at the same time I'm sure there is a common point where they are all connected to the battery, i just can't find it. All fuses have been checked, replaced and rechecked. I'd like to be able to fix it without buying a wiring harness. Any help is appreciated.
