Hahaha, my thoughts exactly! Thanks guys!!
Well, I moved on from the wiring, figuring I'd have better luck sorting through it with the engine/trans out of the truck.
This weekend I started on fixing the firewall. Was pulling a dent I found when the stud pulled the sheet metal apart.
Ground off the paint and bedliner/undercoating crap to find some pinholes. Cut it out and made a patch, which lead to blow outs. I hate thin sheet metal and rust!!!
Well, I ended up with this.
And got it all finished up here
I guess GM never meant for these panels to be flat, so the entire blower motor area is low, which is why the welds still show up. I didn't want to grind through any metal, so I'll have to try and work the steel as best I can. Thankfully I'll be making a panel to cover most of this anyway. Heck, it might have been easier to replace the full face of the firewall in this area, maybe even this section of the cowl too.
