Disable rear PDC via hitch light, where to plug in?
I have an aftermarket hitch and bike rack on my X1, and it makes the rear PDC make a continuous tone everytime that I go into reverse...very annoying.
I've read over on Bimmerfest that several people with X3/X5 have had success with adding a simple $10 tow light and connecting it via a "4-pin to 7-pin" connector, which adds enough resistance/draw to make the ECU think there is a proper trailer turn signal.
Has anyone done this before? Where should I be looking for the connector?
Any help would be much appreciated.
