There's a wire underneath that was added on to the red wire (I think the aftermarket stereo) and it burned all the coating off of it. Also, before I changed the voltage regulator the headlight ( left) went out and would only work on highbream. The headlight came on once I replaced the regulator. However, when I burned that wire and smoked out the cab it went out again. Now what are your thoughts? This is frustrating me.

Well the sensible thing is to disconnect the added red wire to the stereo. It's either shorted to ground or if it's an amplifier power wire, it's probably pulling too many amps for the wire and the ignition switch to handle. As I said earlier, you probably have a key off drain that's developed into a full blown short to ground. The red wire that the stereo was connected into is the hot wire from the battery which would make the stereo wire a key off hot wire as well, and the drain would be a key off, or on drain.
The headlight problem I suspect is a poor ground on the left headlight.
Look at the 5 wires on the left headlight connector ( It's not a GMC is it) and trace the black wire to the ground on the radiator support. Clean this up and check the low beam to see if it's working. Check the connector as well for corrosion and clean it if need be.
