A 20 A fuse is assigned to the fuse carrier.

Component Identification:

F34f25 Fuse 25

18. Route stationary heater wiring harness (1) along existing lines to the right rear wheelhouse to the right rear axle electrical distributor connector (X62/33, see magnified view) and fix in position.
19. Remove the orange-colored lip from the second plug position from below out of the rear axle electrical distributor connector, right (X62/33) (is no longer required).
20. Insert blue, 4-pin coupling (50) from the stationary heater wiring harness (1) into the rear axle electrical distributor connector, right (X62/33).







21. Route stationary heater wiring harness (1) along existing lines over the wheelhouse into the right of the luggage compartment and fix in position.
22. Disconnect telephone antenna connector (A2/49a1x1) (see magnified view).







23. Fix on-board antenna line (52) coming from the telephone control unit with felt strips on the right wheelhouse as per picture.







24. Remove the red strip on the back of the telephone/portable CTEL/STH radio remote control antenna splitter (A2/53).
25. Clip telephone/portable CTEL/STH radio remote control antenna splitter (A2/53) into the existing bores at the side panel.
26. Press antenna splitter onto the side panel.
27. Connect the antenna line (51) which comes from the antenna to the central connection of the telephone/portable CTEL/STH radio remote control antenna splitter (A2/53).







28. Connect antenna line (52) which comes from the telephone control unit to the connection marked in black (sw) of the telephone/portable CTEL/STH radio remote control antenna splitter (A2/53).
29. Connect the antenna line (53) (from stationary heater wiring harness) to the connection marked with red of the telephone/ portable CTEL/STH radio remote control antenna splitter (A2/53).










30. Push STH radio remote control receiver (A6/1) onto bracket (55) until it locks in position audibly (Figure on left).

The 6-pin, black coupling and the antenna line (56) of the stationary heater wiring harness (1) are not connected until the STH radio remote control receiver (A6/1) is programmed (Figure on right).

31. Mount bracket (55) for the STH radio remote control receiver (A6/1) on existing studs on the right wheelhouse and secure with two plastic nuts (54) (Figure on left).
