Hello, I recently replaced my factory uconnect 3 radio/ 5" touchscreen radio with an android unit. The factory unit was not working when I bought the truck. My new radio has the standard 3.5mm mic connection but I would like to use the mics or mic on the factory rear view mirror. Does anyone have the wiring for the mics I'm assuming the original is somewhere on the factory wiring harness that goes to the back of the radio. Thank in advance.

There are 2 mics in the mirror. They come from the mirror to the radio in the large connector 1 on pins -29 and +30 and on pins -39 and +40. Attached are both of the color diagrams for the two harnesses they used in those trucks, they used the same pins but different wire colors in some builds. I would look at the wiring for the new unit and see which is the positive and negative mic inputs and pic one of the pairs out of the OE wires to use.
