Trouble Finding Cold Side of Brake Light Switch on 2015 Kia Sorento

Question:

I am installing a brake a controller on my TV. A 2015 KIA Sorento. Using a circuit tester I find three wires on my brake switch are hot. The forth is not and when I press the brake it does not light. Does that make any sense? Any help would be welcome.

You may need to try to find some other wiring on your 2015 Kia Sorento until you find a wire with your tester that only gets hot when your brake pedal is pressed. I tried looking up what the wire color might be for cold side of your brake light switch but I wasn't able to find anything.

If all else fails you can install the Roadmaster Universal Stop Light Switch Kit # RM-751000 for your brake controller. This mounts on your brake pedal arm and simulates the cold side of the brake light switch so you can connect that function to your brake controller.
