The cable lug to the fuse box (40) should be crimped to the two supply lines (red).

1. Route the branch-off line of the supply lines (red) of the wiring harness for the illuminated door sill molding (1) to the rear signal and acquisition module (SAM).
2. Route both branch-off lines of the illuminated door sill molding wiring harness (1) to the door contact switches.

   The longer branch-off line is routed to the left door contact switch.

3. Guide branch-off line with brown and black/red wire (br, sw/rt) from the illuminated door sill molding wiring harness (1) to the right door contact switch (S17/4) and secure to existing wires.
4. Tie up standard wiring harness of right door contact switch (S17/4) approx. 60 mm and expose the brown and gray/black wire (br, gr/sw).
5. Using a cable clamping connector, connect the brown cable (br) from the wiring harness for the illuminated door sill molding to the brown cable (br) of the production wiring harness. Using a cable clamping connector, connect the black/red cable (sw/rt) to the grey/black connector (gr/sw)

8. Connect the 2-pin coupling 11) to the mating plug (5) of the lamp strip, secure the cable and the connector (5, 11) with felt strips (see arrows in left Figure).
9. Secure clamp connection at the right door contact switch wiring harness (S17/4) with felt tape to body.
10. Wind felt tape around converter (7) and secure with tie straps to existing wires (see detail).

12. Tie up standard wiring harness of left door contact switch (S17/3) approx. 60 mm and expose the brown and the two gray/red wires (br, gr/rt).
13. Guide branch-off line with brown and black/red wire (br, sw/rt) from the illuminated door sill molding wiring harness (1) to the left door contact switch (S17/3) and secure to existing wires.

    Both gray/red wires (gr/rt) can be used as desired for the connection to the black/red wire (sw/rt) from the illuminated door sill molding wiring harness (1).

14. Connect both brown wires (br) and one of the gray/black wires (gr/sw) to the black/red wire (sw/rt) using one cable clamp connector each.

15. Wind felt tape around converter (7) and secure with tie straps to existing wires (see figure cutout).
16. Secure clamp connection at the left door contact switch wiring harness (S17/3) with felt tape to body.
17. Connect 2-pin connector (11) to counter connector (5) of the lamp strip and secure cable with the connector using felt strips according to figure (see detail).
