- Add 4 wires (X12*B): K-CAN +/- (pin 5, pin 6) to passenger controller*, +12V wire (pin 7) to power ///M badges to each seat controller
- Remove/isolate wire from pin 4 (LIN) in passenger seat controller (X12*B) - Carbon buckets have no footwell light.
- VO Coded 48C (Carbon Buckets), remove 481(Sport seats) or 712(M Sport seats), and 488 (lumbar) via BimmerUtility
- Enable occupancy sensor on passenger controller via ISTA (clear any airbag error)

* ventilated seats, or M Sport seats have controller on passenger-side, CAN wires are already in there so no need to add CAN wires.
