The trailer brake controller allows brakes to be applied on to the trailer at the same time as the truck. It also lets you control the sensitivity of the brake or how hard the stopping power will be applied. Programming is necessary after installation and will require the vehicle to be connected to a computer to do so. The trailer brake controller module can easily be located at the dashboard at the left side of the steering wheel.
