Alright. I've spent all day long trying to figure this out and am still stumped. Please, if you have any suggestions for things to check let me know. Getting desperate at this point.

Car:1989 S13 Hatch

Issue: I have no power to roughly 70% of my interior wiring. I had a shop put a cage in my car and after reassembling the car I have loads of electrical issues. The car had zero issues before being taken apart. Wiring harness was not removed from the car, but the dash bar was, and all electrical components removed.

Things working: Headlights turn on, brake lights, hazards, horn, blower motor controls, ignition, and starter (car will start)
-Also, all of these things still work, even with both the Accessory and ignition relays unplugged....

Things not working: Dash lights, windows/mirriors, taillights, interior lighting, wipers, blinkers, headlight motors, mirror adjustment controls, cig lighter

Things checked/gone over: All 5 interior grounds, all engine bay grounds, checked all plugs under the dash for firm connection, 75 AMP alternator fuse is still good, checked all fuses in the kick panel, and all fuses in engine bay.

I've been studying the wiring diagrams all day and checking anything that I can think of. Please help if you have any suggestions.

Thanks!

Figured it out after two days. The screw on the front of the SMJ board had backed out and was not the giant harness plug was not fully seated.
