On your 2005 Dodge Ram 2500, the fuses that protect your tow package circuits are located in the fuse box located under the hood. The fuse box should have a legend on the inside of the cover that outlines which fuse protects which circuit.

If your fuses are blown, I would recommend to check all of the wiring and the connections for your brake controller and the 7-Way connector to make sure that none of the wiring is shorting out and causing the fuses to be blown.

I would also recommend to test your brake controller to make sure that the problem is not with the unit itself. If you have the Tekonsha P3 Brake Controller, part # 90195, it has diagnostic options that can be run to determine if there is a problem with the brake controller.

I am including a link to the instructions on the Tekonsha P3 brake controller and a video link of how to test your brake controller.
