Thank you Ruth and Bob. But the mystery I am trying to solve is why are my reverse lights coming on when the pushbutton controller is not in the car? It would seem to me that the circuit would now be open if the back-up switch was on the controller when I removed it. It appears instead that my aftermarket wiring harness has a direct connection from the light switch to the connector behind the left kick panel. Perhaps whomever the vendor was left it to the installer to splice into the white wire to install the switch? Odd...
Oh and Bob if you want that controller you are welcome to it once I find it. I believe my Fury is past the point of a restoration back to a PB tranny.
Thank you,
Jim
