I know zip about wiring a guitar and really need some help. I am restoring an Airline Archtop and have decided to add a Humbucker and volume and tone controls. The volume and tone tone controls came prewired on a pickguard and the Humbucker has 3 wires black, red and ground . I have attached a picture . So anyone who can tell me how to do this, please do so. It would be greatly appreciated.
