Hi Meade, You can easily bypass the fader switch... In earlier cars (which I'm familiar with) the fader switch wiring harness has connections to the rear speakers in the center console. If you work with the wire, you can stretch them up to the radio. No need to run new wires to the rear. I run new wiring to the fronts, since the factory wiring is part of the factory fader harness. Normally I do this with out cutting anything (I have lots of the male factory speaker connectors, and access to the original crimp tool for them) so I can return the car to original.
The original style speaker connectors are labeled + and - if you look very carefully at the plastic pieces. Good luck!
