Snake Pit




Looked under the dash (light switch) and replaced the brake light switch with no soap. There is a snakepit of spliced and disconnected wiring under there.
QUESTIONS:
1. Is there a wiring color code to be had in order to see what goes where?
2. The #2 fuse slot (brake lamp) on the side dash panel was Frankensteined together. Trying to remove the fuse box to attempt a repair. Is the fuse box integral to the light switch, or can it come out seperately?
3. Is there a recommendation for an afforadable multimeter?
Any help is appreciated.








Perhaps I'm missing something, but can't find the dash fuse box (colored wire noted) in the diagrams. Is it not called "fuse box"? If not, how is it termed?
One issue is that the wiring was jury rigged with different than the factory colors.
