997.2 V1 Radar Install

[SC_Driver]

Greetings,

I'm attempting an V1 radar detector install into a '09 997.2S with auto dim mirror using a Blendmount mirror tap kit. I removed the trim from the point where the mirror is mounted to the windshield and found a plug in the bottom back of the mount. A pic follows. Has anyone had experience with this plug? I believe the thicker brown wire is power but I don't know which wire is ground. The picture is looking up from below the mirror. Thanks, Wayne

Porsches brown wires are typically grounds. Unplug harness and use a meter to check wires for voltage.
