3. Remove the old switch from its mounting position.
4. Install the new switch and reconnect the wiring harness.
5. Test the operation of the parking brake light.

5. Inspect Wiring and Connectors

Tools Required: Multimeter
If electrical issues are suspected:
1. Use a multimeter to check the voltage at the parking brake switch connector.
2. Repair or replace any damaged wiring or connectors.
3. Confirm all connections are secure.
