- Disconnect all connector plugs and wires from the legacy ICM (P/N 42001-0100) and remove the two mounting screws.
- Install the new ICM (P/N 476221) into the heater Junction Box compartment and secure it with the provided screws.
- Connect the wire adapters (P/N 476208, 476202, 476206) to the corresponding terminals on the new ICM and then connect the other ends of the wire adapters to the existing wire harness as instructed in the manual.
- Reassemble the heater control panel assembly.

4. For Australia models:
- Follow the same steps as mentioned in the USA model instructions, but use the appropriate parts and wire adapters (P/N 476207, 476213) for the Australian ICM (P/N 476222).
