Adjusting the Power Output on a P3 Brake Controller for Heavy Trailer and 2012 Ram 1500 Sport

Question:

I am unable to switch between light and heavy trailer on my 2012 dodge 1500 sport. How do I switch between the two?

On the P3 brake controller # 90195 you will first set the power to the brakes before setting any boost setting. Set the output to 6 then tow the trailer in an empty parking lot at 25 miles per hour and fully apply the manual override (without using the brake pedal).

If the brakes lock up then adjust the power down. If they don't lock up adjust the power up. You want the brakes to be at a point just under lockup.

Then you can select boost. Boost starts the braking at a higher amount of power instead of ramping up from zero. Push the boost button, upper right button. On the display you should see B1, B2, B3, or nothing. Nothing means no boost and B3 is the most aggressive boost setting.

If the issue that you are having is on a factory integrated brake controller you will need to consult the 2012 Ram 1500 owners manual or a Dodge technician since we do not have much experience with the factory integrated controllers.
