I have a 2020 1500 Laramie with the OEM trailer brake controller. This truck was purchased used and from the build sheet shows, it was installed at the dealer. If I use only the trailer brake controller on the dash, the brake lights on my travel trailer do not light up unless I'm using the foot pedal. Can someone verify if the brake lights come on a trailer if ONLY the trailer brake controller is used. Much appreciated. Every other vehicle I've ever towed with the brake lights come on with the controller.
