Does anyone know if there is a 'lead wire' for a third brake light on a camper shell (topper) on the wiring harness, 2019 Titan" ? Dodge/Ram provides a wiring sticking out of the wiring harness for such a hook up. Does Titan provide such an item? I checked all of the visible wiring harness around rear bumper and frame rails. Thought I would check before I lower the rear tire for further searching. Any and info greatly appreciated.
