Class C brake controller

[Tacouser]

I have a 2017 Four Winds Class C. I want to pull a car dolly with electric brakes. Is there a wire harness behind the dadh to hook up a brake controller. If there is where is it?

Yes, if you have an E450 chassis, remove the coin holder at the top of the dash. I modified the coin holder to hold my Prodigy controller and bought the conversion cable (Ford plug to Prodigy) on Amazon.
