    Default 2015 Jeep Wrangler JKUR - Install Mopar 7 Way trailer harness and Brake controller

    I am picking up a Mopar wiring harness today at the Dealership. I've read several different writeups on the install process. My 2016 F150 was easy plug and play with my brake controller... Does anyone have experience with install of a Brake controller in 2015 JKUR with Max tow package? I am guessing there is not a plug in already in the jeep.?

    Any tips or suggestions on adding the brake controller? it was too easy with the Truck.. so i guess i wont get off as easy.

    No plug & play. I went through the Fire wall on driver side. Inside engine compartment at drivers side you'll see a large rubber grommet. This carried wiper fluid to the back. Put a clothes hanger through there and it should enter the cab. As for the controller, I use a prodigy 2 because it allows me to unplug it and store it in the console. I actually never permanently mounted it. It just sits next to the 4wd shifter when I need it.
