OIs an In-Cab Brake Controller Required to Use the Autowbrake Electric Brake Controller # 3430001


I think part of my question has already been answered. For example, if one has factory 7 pin wiring on the tow vehicle, but No in cab controller, just plug trailer 7 pin connector into tow vehicle 7 pin connector after Autowbrake has been installed and you are good to go?

You do not need to have an in-cab brake controller for the Autowbrake Electric Brake Controller # 3430001 to work. The wiring on the unit will connect to either a junction box or just splice into the trailer wiring behind the trailer side connector. I have included a diagram showing the wire functions. Once it is installed you would plug your trailer into the tow vehicle and you're ready to go!
