Like others have said, you will have to use a magnet to "fool" the controller into thinking that they are regular electric brakes. If you don't, you will fry your trailer brakes....ask me how I know. I have EOH on my 40' gooseneck and they installed the magnet up on the frame by the breakaway box, works perfectly. Before I knew of this trick I bought a prodigy p2 that has a setting for EOH built in to the controller. 2011 3500 dually.

Yeah too useful, just made me spend more money and say screw it buy a 2015 😝
