My 2017 Service Manual seems to have omitted that info....it appears to be connector "X3" of the A11 Radio Module, but there is no info on it in the wiring diagram of the Radio/Infotainment section, or a connector pin-out diagram in the connector section.
The 20 pin connector is X1, and carries power, aux audio input, and some other signals.
The 8 pin is X2, and it connects the MOST digital audio data bus to the amplifier, and the HMI module.

It's not in the 2014 Manual either. Nice picture of the radio unit but it does not give title to the connectors on the unit. Sigh...
