I too am running into an issue. Seems the Bimmer I bought HAD a power antenna, but the previous owner removed the motor. I was trying to re-install a power antenna, however the "wire" that comes out of the back of the deck, I do not know which wire to hook to. Color's I have seen in previous postings seem to all say white. Is it plain white? No lines or stripes on it? I have the antennea installed, and hooked up in the trunk, but I can't get switched power to it.
