Is it possible or has anyone tried to wire a radar detector directly into the phone-cable looking wire the runs to the rear view mirror to power the reading lamps?

You could just stick a detector in there and plug it into the cig lighter, but for the detector to see out the REAR windshield you'd have to mount it HIGH on the front windshield. I dont feel like staring at the power wire hanging from it all the way down to the cig lighter... it'd only make sense to tap into the juice for the reading lamps, right?
