Hello! I'm trying to install a Mirror Tap to power my radar detector, and I'm hoping someone here knows the correct wires to tap on the back of the mirror. I've tried using a multimeter, but the space behind the mirror, the short cable length, and the tiny plug make it virtually impossible to do. I'm doing this on a 2016 Mazda6 GT with the technology package, so it already has the OEM auto-dimming mirror. The only pictures I've seen show the molex plug for the mirror you can install yourself, which is different than the one that comes pre-installed with the car.

If anyone knows the right wires for switched 12v and ground, you'd save my sanity!
