Once you’ve connected the power source and the wiring harness to the light bar, you should be ready to go. Before you flip the switch, however, it’s a good idea to double-check the connections to make sure everything is correct. If you do find any issues, you can refer back to the Whelen 9000 light bar wiring diagram to troubleshoot them.
