Anyone have a w211 wiring diagram? For factory installed microphone wires.
Installing an Alpine HU in my w211 today and while I could run the aftermarket microphone up the Abeam to the rain sensor, id much rather tap in to the factory installed microphones. The wiring is going to be in the trunk, but I am not exactly sure where. Has anyone else done this before? Anyone have a wiring diagram?
Thanks
