i would just start pulling down bundles and checking for shorts dude..
sounds like a major issue, check where the wires are folded, and where they go close to high vibe/rub areas.

you gotta just start form the beginning and have a big pack of spices and heatshrink.

sorry to tell you man, gotta work from the beginning, hey here's an idea start at the fuze box and work your way out.

good luck
