Heater wiring problem

Well I just pulled out my 77 K-20 to get it ready for winter and decided to fix the PO's "fix" for the blower hi-med-lo switch. He just had a wire run from the post on the blower motor to the bat. to a toggle in the cab so it only had high. Well I pulled the dash apart and its a mess. Burnt connectors, wire cut all over. I dont know where half this stuff goes and what its supposed to look like. Does anyone have a wiring diagram for that or know where I can just get a new harness for that circuit. Also the fuel gauge is burried past full. What cause's that and is there a diagram for that. Thanks for the help
