Retrofit fiber optic cable wiring harness - AN82.70-P-0002-01PPA

Prepare fiber optic cable wiring harness (1) as shown in figure.

Fig 1: Fiber Optical Cable Connection Diagram
Route fiber optic cable wiring harness (1) in vehicle as shown in figure.
Shown on sedan

Fig 2: Identifying Fiber Optic Cable Wiring Harness Route - Shown On Sedan
Check fiber optic cable routing in trunk
In this case install only the telephone interface (A34/4).

Illustrated on station wagon

Fig 3: Identifying Voice Control System Control Module - Illustrated On Station Wagon
Check fiber optic cable routing in vehicle.
The maximum station sequence is:
- Radio (A2)
- Telephone interface (A34/4)
- CD changer (A2/6) (if installed)
- Radio (A2)
  
  Fig 4: Identifying D2B Fiber Optical Cable Connector
Expose the two fiber optic cable connectors D2B (X39/43) in the area of the cable duct of the right rear door and check the routing direction.
The fiber optic cables routed toward the front of the vehicle lead to the radio (A2) or the CD changer (A2/6).The fiber optic cables routed to the rear to the trunk lead to the telephone interface (A34/4).

Fig 5: Identifying Red And White Inserts
Check the fiber optic cables leading to the front to the radio (A2) at couplers A and B.
Find the coupler (B) that has a red insert (rt) on the radio side (A2) (arrow) and lay aside (it is not altered).

Fig 6: Identifying CTEL (TEL) Interface
Remove the white insert (ws) originating from the radio out of the production coupler (A).
Insert the removed white insert (ws) into the new coupler (N) for the fiber optic cable wiring harness (1) and close the coupler (N). Remove the green cover cap from the white insert (ws) of the fiber optic cable wiring harness (1) and insert the white insert (ws) into the old coupler (A) and close the coupler.

The nominal configuration in the vehicle now is:
- Radio (A2)
- Telephone interface (A34/4)
- Voice control system control module (A35/11)
- CD changer (A2/6) (if installed)
- Radio (A2)
