Success!  So far.  I pulled apart the MFS harness and found the blue wire.
I put 12V to it, and with the car running the backup lights came on. You
wouldn't believe how excited I was to see those lights on.

I still have to actually run the wires from the backup switch on the
transmission to 12V and the blue wire, but the difficult part of the
puzzle is solved.  And I need to dig deeper into the harness to find
the wires for the start relay (or jumper the starter relay itself).

Thanks to everyone for their help and insight.
