wiring aint hard, it’s a loop. complete the loop, things work. I forgot this ground when swapping in the dash harness. It was a right pain in the arse to get to, but I knew where it would be, and that a missing ground was the only thing that could have caused my problems.

bolted in place, and just like that my power windows, power locks, and power mirrors are all working!

100% I was to blame, but I also fixed it. So all is well.
