21.1 Only on vehicles which do not have any switches in the lower control panel control module (N72)

Component Identification:

An auxiliary cable harness for the lower control panel (2) must be routed from the center console up to the left footwell.
- Connect auxiliary cable harness for lower control panel (2) to the branch-off line for the lower control panel control module (N72) in parallel with the branch-off line for the taximeter (A50) on the wiring harness for the taxi frame floor system (1) (see single arrow on far left).
- The branch-off lines of the auxiliary cable harness for lower control panel (2) for the interior fuse box (F34), the voltage distributor connector CAN (X30/7) and ground connection of left front footwell (W15/2) are connected along the wiring harness for the taxi frame floor system (1) up to the left footwell (see arrows below).

Component Identification:

22 The cable branch-off line for taximeter (A50) of the wiring harness for the taxi frame floor system is routed on the right of the AC box along existing wiring harnesses to the ashtray housing of the center console and is fixed in position.

The cable branch-off line for the lower control panel control module (N72) is, if retrofitted, likewise routed with the cable branch-off line for taximeter (A50) to the shift lever and fixed in position.

23 Route the cable branch-off line for the radio data transmission keyboard (A49/5) and credit card reader and printer (A50/2) of the wiring harness for taxi frame floor system, left of AC box to the vehicle's own wiring harness to the stowage compartment/center armrest compartment and fix in position.

The cable branch-off lines for the credit card reader and printer (A50/2) are routed and fixed in position in the center armrest compartment when installing the center console.

24 Route the wiring harness for the taxi frame floor system (1) as per the illustration between the AC box and cable duct towards the left A-pillar.

The wiring harness for the taxi frame floor system (1) must be routed under the four studs.

25 Wrap felt tape around the four studs of the center wiring duct (see direction arrow of illustration cutout).
26 Fix wiring harness of taxi floor frame system (1) in position at existing clip holder with tie straps (see illustration cutout).

It must be ensured that the wiring harness for the taxi frame floor system (1) cannot contact or chafe on any sharp edges.

Contacting only takes place if this wiring harness was retrofitted.
- Connect the brown line to the ground (left footwell) (W15/2) (see magnified section below).
- Plug the green fuse board (56) in plug position 39 of the interior fuse box (F34).
- Assign green fuse board (56) with a 5 A fuse.
- Connect 2-pin coupling in the free plug position of the voltage distributor connector CAN (X30/7) (see magnified section above).

The cable branch-off line with connector for the emergency alarm system/activate button connector (X42/8) stays in the left footwell.

30 Expose cable duct to the left front door.

Remove damping material carefully from the A-pillar and reinstall later in the A-pillar.
