No. You'll have to wire for the brake controller. The easiest place is under the dash at the brake pedal. Tap into the micro switch there and then run that to your brake controller. You'll then need to run a line from the brake controller to the back of the Durango to the 7 pin plug. You'll have to run a 12 volt line to your brake controller too along with a ground wire I think.
One of the pins on the 7 pin plug is reverse lights so you don't have to use that one.
If you buy a 7 pin plug to mount on the back of your Durango, it will have a pin out in the instructions. Mine was a 4 pin and I changed it to a 7 when I got it.
Iirc, you have to add the line from the brake controller, 12 volt, and a ground. The rest is already there in the 4 pin.
Hope that helps.
Oh, I took the ash tray out of mine and mounted the Prodigy controller there. It looks great.
