There's a thread currently going on regarding MC9 backup lights. Check the info there.

First thing I'd do is get a copy of the schematic. Email me offline if noone sends you one.

I'd check the transmission switch, since it supplies ground for the the backup lights and beeper.

As for the tail lights... that one may not be related, but again, the schematic is where you need to start with a probe.
