This is a sample of what I'm dealing with (this is what it looks like currently):
The car supposedly didn't even *have* a fuse block in it when it was built (nothing fused). So, one of the previous owners put one in and rewired things a bit. It's a good idea indeed, but not exactly done in a super-logical way.
I've had to go through each component on the car, test it, check the wiring, and figure out how everything is all wired up. I'm working on an "electrical manual" that details each part, the part number, its individual wiring inside, etc:
Also, a spreadsheet tracking the current (no pun intended) status of each component:
