I would not recommend using the sunroof wiring - there is some software
control of the sunroof operation, and you don't want to risk
inteferrence.

Instead I use the power lead that is for the optional "universal
transmitter" (garage door opener) that also gets mounted in that upper
console panel.

The wiring for it should already be there - small 2 wire connector
(green/white & brown wires). Green/white wires always have power with
the ignition.  There is a separate fuse for this circuit - in fuse panel
above the glove compartment.


Hope that helps.
