Carefully replace the cover panel and secure it with screws. Make sure everything is neat and tidy to allow proper airflow and functionality.

Testing Your Installation

After the installation is complete, it's time to test the new wiring harness. Restore power to the unit and turn on the AC. Monitor its operation to ensure everything is functioning correctly. If you encounter any issues, double-check all your connections and test with a multimeter to troubleshoot as needed.
