Does anyone know if there is any 12v that I can tap into on the rear hatch if I wanted to put one of these on the rear? I've got a 2011 SL.

Wiring was very easy. My non-homelink mirror only had two wires; a black wire with a red stripe closest to the passenger side of the car and a black wire closer to the driver's side. The black-red is positive and the black is ground. I simply removed about 1/8" of insulation from both wires, wrapped the + and - from the transformer around each respective wire, soldered and taped. Done. The transformer gets power in "on" and "ready to drive" mode, and not when off or in accessory mode, which is perfect.
Keep in mind the one I posted is for micro-usb devices, which is exactly what my dashcam is. There might be mini-usb models available as well.
