Expand fiber optical cable ring for component that is to be retrofitted - AN82.64-P-0001-05N

From the D2B wiring harness (10) that was ordered for retrofitting purposes, only the second D2B fiber optical cable module (8)  with a length of 840 mm is needed between the D2B coupling (12) by the sound amplifier and the D2B coupling (14) by the CD changer.

The D2B wiring harness (10) shown in the picture is designed for the maximum D2B ring.

The lengths of the individual modules are listed on the model plate (B) at the D2B wiring harness (10) in the order of the appropriate individual modules in the fiber optical cable ring.

1. Branch off the fiber optical cable module (8) with a length of 840 mm from the D2B wiring harness (10).
2. Unlock retaining clips (11) from D2B couplings (12) and (14) (arrow).
3. Remove D2B fiber optical cable module (8) from the D2B couplings (12) and (14)
4. Remove D2B coupling (14) from the D2B wiring harness (10).

   The remaining D2B wiring harness (10) is no longer needed.

   D2B fiber optical cable module (8) with a length of 840 mm and D2B coupling (14) will be needed later for extension of the D2B ring in the vehicle.

5. Unscrew mounting screws (2, 16) and nut (17) of the sound bracket (6).
6. Remove sound bracket (6) with sound amplifier (A2/13) and TV tuner (A2/42) (for vehicles with TV tuner (code 860)) from the wheelhouse recess.
7. Detach D2B coupling (13) at sound amplifier (A2/13) and expose D2B fiber optical cable module (7, 9) by approx. 300 mm.
8. Release D2B coupling (13) and remove D2B fiber optical cable module (9) with white insert and set aside.
9. Insert white insert of the new D2B fiber optical cable module (8) with a length of 840 mm into the D2B coupling (13) and lock D2B coupling (13) again.

   D2B fiber optical cable module (8) had previously been taken from the D2B wiring harness (10).

10. Reconnect the D2B coupling (13) to the sound amplifier (A2/13).

11. Insert the red insert of the D2B fiber optical cable module (8) and the white insert of the D2B fiber optical cable module (9) into the new D2B coupling (14).

    D2B coupling (14) had previously been taken from the D2B wiring harness (10).

    D2B coupling (14) will be connected to the CD player with changer (in trunk) (A2/6) later on (pictures with CD player are used to further illustrate the situation).

12. Attach D2B lines with adhesive felt tape (arrows).
13. Fasten new tie strap (15).

    Do not buckle or extend fiber optical cable D2B, routing radii have to be larger than 

    25 mm! 

    The information flows from white to red. The beam of light always has to enter the fiber optical cable in the white insert and emerges at the red insert (inserts are coded). 

    The inserts cannot be separately changed! As soon as an insert is removed from a fiber optical cable module, the fiber optical cable module should be exchanged. 

    The sound bracket is reinserted and mounted into the wheelhouse recess later when the CD player with changer is installed (in trunk) (A2/6).
