   The two branch-off lines form the wiring harnesses for the left front illuminated door sill molding (E17/47) and the right front illuminated door sill molding (E17/48). The longer wiring harness is intended for the driver side. The rest of the wiring harness is no longer required.

2. Extend each of the brown lines (BN) with a commercially available brown line and a potential distributor (14) by 1.10 m (42.90 inches).

   Diameter of commercially available brown line 0.75 mm ² (1.48 kcmil).

   Only potential distributors (14) from the basic wiring harness repair kit or the supplementary wiring harness repair kit for passenger cars are to be used.

3. Wrap each of the gray/white lines (GY/WH) and the brown lines (BN) starting at the black 2-pin connectors (12a, 12b) at a length of 2 m (78.74 inches) using felt strips.
4. Connect black 2-pin plug of left front illuminated door sill molding (E17/47) to black 2-pin connector of gray/white and brown line thus establishing the electrical connection of the left front illuminated door sill molding (E17/47x1).

   The longer wiring harness is intended for the driver side.

5. Clip electrical connector of left front illuminated door sill molding (E17/47x1) into bracket of cable duct as shown.
6. Route gray/white line and brown line on left between cable ducts and floor covering on left into rear area.

   Use a pull-through device.

7. Connect black 2-pin plug of right front illuminated door sill molding (E17/48) to black 2-pin connector of gray/white and brown line thus establishing the electrical connection of the right front illuminated door sill molding (E17/48x1).
8. Clip electrical connector of right front illuminated door sill molding (E17/48x1) into bracket of cable duct.
9. Route gray/white line and brown line on right between cable ducts and floor covering on right into rear area.

   Use a pull-through device.

10. Install a commercially available round cable lug Ø 6 mm (13) on the two brown lines (BN) in each case.
11. Lift rear floor covering.
12. Route the two gray/white lines (GY/WH) to the rear control unit (N10/8) and fix in place using felt strips.
13. Route the two brown lines (BN) to the right rear seat ground point (W17) and fix in place with felt strips.
14. Connect two brown lines (BN) to right rear seat ground point (W17) .
15. Disconnect curry yellow 52-pin connector (1) from rear control unit (N10/8).

17. Install left contact of gray/white line of left front illuminated door sill molding (E17/47) in contact cavity "12" of gray contact carrier (1a) (arrow B).
18. Install right contact of gray/white line of right front illuminated door sill molding (E17/48) in contact cavity "11" of gray contact carrier (1a) (arrow A).
19. Install gray contact carrier (1a) into curry yellow 52-pin connector (1).
20. Connect curry yellow 52-pin connector (1) to rear control unit (N10/8).
