What about the loose cables that nothing is attached to?
The 1 white wire and the 2 black wires with a ring at the end.
If you're talking about the white wire on the volume control, I think I covered it in the last sentence. That is where the center lug(s) of the toggle switch needs to be connected.
The two black wires with a ring at the end in your diagram is probably where the pickup ground wires connected and would be covered under "solder the black and bare wire of each pickup to your ground connection on back of the volume control". You can either splice to these wires or remove them and solder the pickup grounds directly to the back of the volume pot - your choice.
Do you have a bridge ground? Maybe a black wire going inside the body wood toward the bridge or tailpiece whatever you happen to have? If so, solder that to the back of the volume pot also.
Yes i do have a bridge ground and thanks for the wiring info.
