You might try getting a Harbor Freight or similar wire tracer tool. About 25.00. Puts a signal on the wires from your mystery switch. and you then can go to the bay you think the wires might run thru or terminate in and locate them. You might then have the "ah ha" moment we have all had with out mystery switches.
