Shown on model 211.2

The fiber optic cable wiring harness (MOST) (7) is routed forward starting from the left of the trunk.
Insert black 4-pin coupling (6) from auto pilot system wiring harness (1) into black 6-pin coupling housing (8) of fiber optic cable wiring harness (MOST) (7).
The black coupling housing (8) is from audio gateway control unit (N93/1). An arrow is located at the side of the black 4-pin coupling (6). This corresponds to the direction of installation into the black coupling housing (8).
Connect the black coupling housing (8) to the audio gateway control unit (N93/1).
Fasten fiber optic cable wiring harness (MOST) (7) as shown on left wheel arch to on-board wiring harness.
The green color coding on the MOST fiber optic cable wiring harness (7) must match the green color coding of the on-board wiring harness (arrow D).

Unclip covering (14) of both on-board fiber optic cable connectors (MOST) (X39/50) in direction of arrow.
Determine which fiber optic cable connector (MOST) (X39/50) contains an on-board fiber optic cable module with the number XX1 or number 4.
Release catch hook (15) of fiber optic cable connector (MOST) (X39/50) and remove on-board fiber optic cable module with number XX1 or with number 4 from fiber optic cable connector (MOST) (X39/50).
The on-board fiber optic cable module with number XX1 or number 4 is no longer required and is to be strapped down in the cable duct.
Install fiber optic cable module with number XX1 of fiber optic cable wiring harness (MOST) (7) into free plug position of fiber optic cable connector (MOST) (X39/50).
Determine which fiber optic cable connector (MOST) (X39/50) contains an on-board fiber optic cable module with the number 14.
Release catch hook (15) of fiber optic cable connector (MOST) (X39/50) and remove on-board fiber optic cable module with number 14 from fiber optic cable connector (MOST) (X39/50).
The on-board fiber optic cable module with number 14 is no longer required and is to be strapped down in the cable duct.
Install fiber optic cable module with number 20 of fiber optic cable wiring harness (MOST) (7) into free plug position of fiber optic cable connector (MOST) (X39/50).
Clip on cover (14) on both on-board fiber optic cable connectors (MOST) (X39/50).
Insert fiber optic cable connector (MOST) (X39/50) into cable duct in area of left rear door.
There are two fiber optic cable connectors (MOST).
Route MOST fiber optic cable wiring harness (7) further into left cable duct in left front footwell.
Route fiber optic cable wiring harness (MOST) (7) from left footwell cable duct along parking brake cable (16) to radio recess and fix in place.
