Electrical Schematic

[coltonk]

I have been working on my new GMC SWB and finally got the engine and tranny in now my problem is all the wires that the previous owner just demolished. Some wires are melted, frayed, or just randomly cut. Maybe some one on here can lead me in the direction of a schematic of some sort to help me get through this process a little easier. I read schematics daily for a living in the Air Force so if I can figure them out on a jet surely i can some how figure this out. thanks for any help.
