Compass/Temp Mirror for 2003 Trailblazer

I'm trying to install a Compass/Temp mirror in a 2003 Trailblazer LS. This mirror requires running wires to a sensor in the front of vechile, and Power throught the ignition swith. The temp sensor wiring was a piece of cake, but I can't find a power lead through the switch that is accessible without tearing the whole dash apart. This device only draws about 100 milliamps, so I could piggyback off of something else. Anyone have a clue?

Well, if you were able to drag a wire all the way from the mirror to the sensor, then you should be able to grab something under the dash for power without taking apart too much. I'm not sure where the fuse panel is in your car, but in my car it's in the driver's kick panel, and right above it there are male connectors for constant 12v+. Maybe you can find something similar?Q: What's the best nation in the world?
