Im close to cutting up my whole harness and rewiring it or buying a new harness
Why would you do something so drastic?

Have you taken the plastics off so you can inspect the PIN connectors and the wiring harness?

Have you checked your resting battery voltage with a multimeter? Had the battery load tested? Cleaned the battery terminals and the main ground bolted to the frame (L) side?
 
Ive also taken off the main ground bolt and sanded and cleaned the area to see if that would effect anything, could my fuse block just have gone bad?
Doubtful. Have you tried restoring the wiring harness by removing all of the aftermarket wiring? Buying a used harness is a gamble in itself. You may get a better one. Or you may get a worse one. There's no way to know until you check each wire. So you might as well do that to the wiring harness you have.

Do you have a service manual or wiring diagram?

Dannoxyz has a great troubleshooting writeup that can help you find the problem.
