What are these wires for?.....

[Riffmeister]

I have black wires running from each pup cavity to the main control cavity, but all they are hooked to is a screw in the body at each end.

There's shielding paint in the cavities and the wires ground all the electronics cavities together.

+1 they're for grounding.

Cool, thanks guys! I'm glad I asked and didn't just rip them out

I doubt you'd notice a difference with them gone, but since they're already there I'd leave them.
