The lines have a cross section of 1.5 mm2 and are twisted with each other. In the area shown here there are two subharnesses with pink lines (rs) and brown/pink lines (br/rs) downstream of the left rear speaker group connector sleeves. Make sure that the subharness routed through the B-pillar to the left rear door is separated.

16 Use a solder connector to connect the pink line (rs) of the standard installed wiring harness, which is routed through the B-pillar to the left rear door, with the pink line (rs) from the auto pilot system wiring harness (1).

18 Use felt tape to insulate the pink line (rs) and brown/pink line (br/rs) of the standard installed wiring harness, which is routed to the front, and route into the cable duct.
19 Detach both pink lines of black 10-pin wake-up signal connector (X30/8) from auto pilot system wiring harness (1) and install in any contact cavity of the vehicle's installed black 10-pin wakeup signal connector (X30/8).

If there is no black 10-pin wake-up signal connector (X30/8) installed in the cable duct, fasten the black 10-pin wake-up signal connector (X30/8) from the auto pilot system wiring harness (1) to the given bracket in the cable duct.

20.1 Strap down violet 2-pin radio 'mute' plug distributor (X30/12) (no longer required) of the auto pilot system wiring harness (1) in the cable duct

For vehicles without code (272) Non-networked telephone preinstallation with telephone antenna or without code (273) Cell phone telephone preinstallation (non-networked) VDA wiring.

20.2 Expose radio 'mute' plug distributor (X30/12) in left front cable duct, separate it and strap down the connector (no longer required) for the vehicle's installed radio 'mute' plug distributor (X30/12) in the cable duct.

For vehicles with code (272) Non-networked telephone preinstallation with telephone antenna or with code (273) Cell phone telephone preinstallation (non-networked) VDA wiring.

21 Connect connector of yellow line (ge) of radio 'mute' plug distributor (X30/12) from auto pilot system wiring harness (1) with vehicle's installed coupling of radio 'mute' plug distributor (X30/12) and insert into cable duct.
