Electrical gremin - lighting

I'm having an issue with the lighting on my M5... two issue, actuallly.

When I turn on the headlights, the cluster beeps and gives me a warning of "trunklid open".
When I put the trans in reverse, the cluster beeps and gives me a warning of "license plate light".

Any thoughts on where to start looking for trouble?

The first thing I'd check is the wiring going to the deck lid from the luggage compartment. Release the black plastic cover over the left hinge and check for frayed wires.
