I doubt that the Superior workers that wired the car would appreciate that remark. Most times, it is faster and more feasible to just remove all the wiring and start over again. Lacking that, then just get out your test light, and start trying to figure it out. You didn't say if it was the original factory wiring, or the wiring that Superior added. If it is the factory wiring that has been hacked, then there are suppliers of reproduction wire harness's for your car. If it is the Superior side of the coach, then it will be a learning experience to deciphering what went where, and how it got there. I suggest using a stand alone 12 volt battery clipped to the wire and the car ground, and then testing with a probe till you find the wire in question. I believe that your car has cloth covered lacquered wiring from the Cadillac factory, so tracing it by colors isn't easy. Usually, they all look the same...
