Wiring Harness routing
 

I recently purchased a 2000 Bravada that had the wiring harness wrapped around the driveshaft. I ordered a new harness from GM and I am having trouble figuring out where everything is supposed to be attached. The block that goes to the distribution panel was easy but there are two wires that I cannot find a place for. There is a red wire with a ring terminal that appears to go to the back stud on the fuse box. Is this correct? There is also a blue wire with no connector on it. Where does it go? I inherited this mess like it is and didn't have the luxury of disconnecting everything myself.

What harness are you talking about? It was wrapped around which driveshaft?

I think you are talking about the headlight/taillight harness. I believe those connectors are for the heavy duty trailer harness (7-pin).

The main wiring harness that starts at the fuse/relay panel with a large red "block" that bolts to the panel and routes down by the engine on the drivers side and goes all the way to back and attaches to the frame in multiple locations with black clips. This also goes to the fuel pump and everything else behind. This harness was wrapped around (mangled and useless) the driveshaft when I bought the vehicle. It has two larger gauge wires (red and blue)that are separate from the block that bolts in. I need to know where these twp wires attach.

As I said, these wires are likely the wires for the heavy duty trailer harness. Unless you are using the trailer harness, they do not need to be connected to anything.

Thats what it sounds like to me as long as your fuel pump is working there shoudln't anything behind that besides trailer wiring

Thank you. I'll give a shot. I didn't want to "power up" until I heard from you guys first.
