Gl post some pics of how you ran the wire, also where to buy the lights looks clean dude awesome job. Those are led? or bulb?
2 x LED, superwhite, ~3V, 20mA. Resistor=330ohm .25W
I guess this is a bit of a technical project, sorry there's no easy way here.

Maplight/sunroof control panel. One clip on either side. The small bundle of wires is the maplight power set. I spliced into these - very short lengths, and very small wires

The hole on the right goes into the headliner in the same compartment as the holes for the sunvisors. With a long narrow stiff wire you'll eventually be able to get to the sunvisor holes



Again, sorry it's a mess
I wired a microswitch that fits into a slot I cut in the back of the mirror assembly. When the cover opens, the back of the hinge presses down about 1/4 of an inch, enough to press the switch.
I used a diffuser as the LED is too dazzling shining directly at the face. The diffuser was a rectangular section of a spare car side light.
I know it's a hack job... Still it works (cheers2)
