Wiring Nightmare

I few years ago the wiring harness in my 91 Caprice Classic caught fire, and since any and all replacements have been discontinued, I've been stuck trying to cut and splice in new sections. Needless to say I'm having almost no luck at all. I have all power options, and a 305 motor. Does anyone know where I can get a complete harness, or maybe just someone who knows how to read wiring diagrams?????????

:banghead:

I'd try a junkyard. You have to get a car that's mostly complete however, as a lot of people like to hack through the harness instead of properly removing the wires when they get something.
