1996 Chevrolet Truck

Electrical problem
1996 Chevy Truck V8 Four Wheel Drive Automatic

I am trying to find a place to get the wiring diagrams for my 96 K1500. I have a few electrical issues and the Chilton book has crap for wiring. I found 2 burnt wires at the multi switch(hi/lo turn). Here is a list of the issues that caused me to tear into my dash:
1. DRL went out years ago.
2. Low Beams went out 2 years ago.
3. Hi beams just went out.
4. Power door locks quit 6 months ago.
All this, I think, started about the time the Clifford alarms system started acting up. I removed it after the DRL and before the low beams.
I asked one of the guys in the local Chevy service dept. And they mentioned a Body Control Module BCM. Is there one in my truck? To me it seems like I have a bad ground somewhere.
Thanks for the help,

Hi, hope that is readable. When the drl relay is not energized, there is continuity for the low beam voltage circuit through the drl relay to low beam.
