I have a 2000 323 Ci and I've got a radar detector mounted on my windshield right under my rear view mirror and would like to wire it in up above rather than have a phone cord hanging down across my dash and plugging into my cig lighter. In the plastic panel where the motion sensor goes, I've found 2 plugs, one black, one white. I am only assuming that one is for the motion detector (which I don't have) and the other is for the Universal Garage Door Opener (UGDO). The 12VDC should be the green/blue wire but there is no green/blue wire in either plug. Is there another wire bundle shoved up in the headliner somewhere that I can't see and have to fish out? Is one of those wires in the two connectors usable? I'd prefer to use something existing rather than run new 18GA wires up the A pillar etc. Any help would be greatly appreciated.
