I bought a Bravada a few months back and a small heater hose deteriorated and caught my wiring on fire, and I have been trying to find another complete wiring harness for this truck. The problem is that this wiring harness from the dealership is discontinued and can't get one for less than $1,800! And when trying to find a complete wiring harness from anywhere else they are only one strip or piece and not a complete wiring harness for everything. With all the color coded connectors as such that plug into the ecm module (computer) and all the other plugs. So, in short, I need to know how to find a complete one either aftermarket, or how to tell a salvage yard what it is I am looking for, or if there are ones I can get out of another vehicle and what vehicles are acceptable to get one out of? Every time I ask a salvage yard or look one up online they are only one strip and not a complete big main or total wiring for the engine that I need! Hope this is enough detail for someone to help me PLEASE!

If the harness goes to the ecm you need to know which one it is it can be the engine harness ecm to body and or chassis harness. You should be able to use one form a comparable gmc envoy or chevy trailblazer or of course a bravado. The bravada has all wheel drive so try to find one like that. From your description it doesn't let us know what harness you need.

It connects to everything from the computer to the transmission or just under the dash. It's the complete wiring on top of the engine and has like 8 different color plugs/connectors, red, black, gray, blue, white, and whatever else color coded plugs. How do I tell if that's body, or chassis harness? Its all one piece and huge

The chassis harness will go down the frame from the fuse box if it goes to transmission it may be just the trans harness it's been along time since I've seen those best bet is take a picture so you can match it with a vehicle at the scrap yard. The connectors may change due to different years. Otherwise you are just shooting in the dark with it. If the wiring burnt it's very possible you fried the modules that went with it. Or if worst comes to worst remove the burnt up harness so you know better what you are dealing with as it sounds like the truck doesn't run anyhow.
