Ok, So I think the red hearing that was tripping me up was this red and white cable that was strapped to the white cable. I don't think it needs to be there, the white SC25 cable is pre made and will fit right into SC27. This Kufatec have it labelled up wrong.
The cable that isn't pre made goes into the X-Contact relay which is relay 644 located along side the fuse box.
Earth cable is self explanatory.
Which now just leaves the 2 pre made connectors for the BCM. Thanks to Pauly, we can confirm that A36 is the heated seat cable and as you can see in the photos in empty, however I don't understand what pin 54 is meant to be for as this slot is already occupied?
