Modify branch-off line, driver side (9.1) and branch-off line, passenger side (9.2) as follows, outside of vehicle.

1. Fit round cable lugs (14) with 6 mm diameter to brown lines (BN).
2. Remove contact springs (13).

   Contact springs (13) are no longer required.

3. Shorten red/black line (RD/BK) and red/white line (RD/WH) by 100 mm each.
4. Extend red/black line (RD/BK) on branch-off line, driver side (9.1) and red/white line (RD/WH) on branch-off line, passenger side (9.2) using one 500 mm long yellow line (YE) each.

   Connect using potential distributors (12); they must be taken from the wiring harness repair kit.

5. Connect 100 mm long red/black (RD/BK) and red/white (RD/WH) lines to yellow lines (YE).

   Connect using potential distributors (12); they must be taken from the wiring harness repair kit. The line colors must be the same at the beginning and at the end of the yellow line (YE).

6. Wrap felt tap (15) around branch-off line, driver side (9.1) and branch-off line, passenger side (9.2), starting from the black 2-pin connectors (8.1 and 8.2) over a length of 800 mm.
7. Wrap felt tape around all potential distributors (12).
8. Install one contact spring (11) each at the 100 mm long red/black (RD/BK) and red/white (RD/WH) lines.
