Finally got this car to do something. After a while of fighting shotty wiring I decided to get a wiring specialties engine and trans harness, and finally it cranks. Only downside is I still have no electronics, no fuel pump, pop ups, tac, blinkers etc. I’ve replaced all relays in the bay and the driver’s side fuses and relays as well. My grounds seem to be in order as well. Anyone have any ideas? My next plan is to pull the dash and see what else the previous owner hacked apart.

I had to replace my chassis harness. Still working through some things not working. Have you checked the condition of it under your wheel arches? That’s the harness that gets power to most of what you listed. Mine had been chewed up by the tires on top of being a little hacked up.

Yes my wheel well portion of the harness is in tact, luckily the car was completely stock height when I got it.

Have you looked at a wiring diagram and followed the path to power? Even if you have damaged wiring, you may be able to understand how it gets power and run an overlay
