You will drill pretty big holes for the bushings for the tailpiece (forget the bridge) to be set in with a mallet... Once the these holes are drilled, the one closest to the control cavity can be hit with a small drill bit, creating a tunnel between the two. I'll send enough ground wire for the whole project, but a piece is run from the control cavity to the closest tailpiece hole... Once the wire is run and just barely sticking out of the bushing hole, set the bushing. The wire will pinch between the wood and bushing. The ground then gets connect to one of the pots. The guitar strings ground the bridge and tuners.
