There are 4 wires behind the switch panel in the patient area that are not connected to anything and a few of the wires that go to the 2 switch panels that have been spliced and rerouted. I want to see if I can clean it up a little.I remember that switch board. Yikes!! It all worked, so I left well alone.
I was able to trace back one of the white mystery wires from the switch panel. The other end was under the dash by the glove compartment. Looks like it was cut. Since it was close to an unused circuit breaker, I placed it back in service as the lead got the switch panel.When I restored the electricals in my 1976, I folded over and taped any "unused" wires "just in case".
