I bought a diamondback body that has the TOM/STP bridge rout and I installed the bridge studs without even thinking about the grounding wire. Is there a hole for a grounding wire to one of the bridge studs and if so which stud does Warmoth use as the grounding wire stud? I cannot see a hole in the control cavity that would lead to either of the bridge studs. The only hole in the control cavity that I can see is the humbucker wire hole.
