Thanks, that's for a 2009? Would it be best to tap into ignition +12v for a radar detector?

Yes, the for 2nd Gen. Tap into the ignition so that it powers up only when the car is running.
There should be just three wires at the connector behind the mirror for all 2nd Gen . What other functions on your mirror other then the regular garage door buttons and auto dimming?
