Retrofit wiring harness - AN82.61-P-0001-01TCZ

Cut pink line (rs) of navigation processor wiring harness (1) as shown in the picture so that 30 mm of the pink line (rs) are left before the sleeving of the navigation processor wiring harness (1).
The cut-off pink line (rs) is no longer required.
Strap down the GPS antenna line (6) and GPS coupling for the navigation processor (9) on the navigation processor wiring harness (1).
The GPS antenna line (6) and GPS coupling for the navigation processor (9) are no longer required.
Check chamber assignment of black 8-pin navigation processor connector (12):
- Chamber 1 brown line (voltage supply -)
- Chamber 2 red/white line (voltage supply +)
- Chamber 5 pink line (MOST wake-up line).
