I don't think it's the main harness? The main harness is different from the A/C harness, right? Lord, I guess I could buckle down and pay the $1,000.00 if it's all the same harness, but wow that's expensive. And it does seem to be two different harnesses....

One of those black plugs, the one that attaches to that 2"/1" metal device, is connected to the A/C system (I think), the hoses that disappear into the firewall towards the part of the A/C system behind the dash (condenser?). And the other end of the wiring harness disappears directly into the firewall. And that whole length of harness is just a melted mess. I don't know if could sort it out.

I'm gonna haul out my CD-ROM manual and get to the bottom of this. I have to wait until my wife gets home, because she has the PC laptop.
