2011 328i with successfully coded combox mod. Previously only had mulf with no TCU. Confirmed mic is in center headliner. However, no mic wires in trunk. How do I connect a the existing mic or do I just add a new one?

I do have 620. Not the other options. Don't know where the voice mic wiring goes.
