If I am to understand correctly, the 2015 ram truck has PWM lighting system. I also come to understand that this is what causes a lighted hitch cover to blank when the right turn signal is on. Does anyone know how to build a PWM adapter or module to filter out everything but the brake light signal or how it could be wired/ Rewired to prevent it from blinking with the right turn signal? The only suggestion I have seen is to run a wire to the 3rd brake light which seems excessive. There should be an easier way without running a bunch extra wire from the cab back is I don't know of any 3rd brake light wire near the hitch, bumper or trail light area.
