Thank you so much for this. I knew things were not making any sense. So is the yellow connector fine left alone and not connected to anything? Some of the other guides suggest that PIN 6 is connected to the blue/white wire on the head unit for antenna control maybe? Should this just be left out completely?
Black / Red 12 Volt Switched Power Yellow Connector C - Pin 6

The external amp gets his audio signal via MOST-Bus. That is the connector in the right top on the picture. MOST-Bus is an audio bus only. It doesn't switch anything on or off.
The external amp (HAES or BOSE) has it's own power supply cables and fuse and CAN bus wakeup.
The power on by the car get both components via interior CAN BUS signal (wake up signal). If you want to power on / off aftermarket audio components like the 986 does via putting the key in the ignition switch you'll need an adapter that generates that internal bus signal to a B+ switch signal.
Also there is a connection between the IC and the CDR23 via interior CAN BUS that shows radio stations and so on the IC.
The yellow connector is for phone, microphone and interior CAN bus. Don't mess with the yellow connector, else you will have CAN bus problems.
