I just bought one to tow my TT. Learned the expensive way that new for 2013 the RAM 1500 uses multiplex wiring and common brake controllers cannot be used with this system. Instead RAM suggests a "universal" brake controller, specifically the Prodigy RF brake controller.

The benefit to this controller is that it mounts easily to the frame, requires no wiring and can be used with any tow vehicle.

The downside is that it cost me $400.00 that I was not expecting to spend!

The RV place showed us a tech bulletin straight from RAM so I know they weren't messing with us (actually recommended another place to buy the controller and saved a few $).

So, even though the new RAM 1500 comes with a tow package, if you don't get the factory installed brake controller as an option with the higher end models, you have to go this route. Dealer also stated that the factory controller could not be installed after.

Well it is apparent that the Italians do not understand trucks and towing.

Must just be the 2013's. Does that include the 2500-3500? I just put a Primus IQ in my 12 Ram 2500. Just unplugged the OEM brake harness from the TBC and connected the Primus up. Just got back from a 200 mile RT and no problems. The EVIC does show the message 'trailer brake service' for about 20 sec then goes away.

My 2013 has the brake controller built in. But I have seen guys add the OEM brake controller to their trucks that don't have it.

You have to have the EVIC on your truck but the wiring for the controller is already there.

Are you sure it was a 2013 model? The dealer said he could do it until the moment of truth and then realized it could not be done on the 2013.

Also, to be fair, I bought an EXPRESS model, which is one of the lowest end models and I can only assume the higher up models include more of these feature automatically.

The 2500 and 3500 trucks prior to 2013 could have the ITBC (integrated trailer brake controller) disconnected by the dealer. To avoid the EVIC problem message described above, the dealer tech had to go in through the CANbus and tell the computer to delete the option code for the ITBC - that way, it no longer looks for it. You can then use any controller you like. I don't know why they would change that on the 2013s.

They completely changed the canbus system this year and it affected a ton of aftermarket stuff. Can't even find an aftermarket harness or dash out to replace stereo and you cannot upgrade from the basic stock stereo to the higher end stock stereos anymore.

I have the express model with the trailer brake controller integrated as long as you have the full evic and not just the tiny screen and dummy lights it should work. The wiring is behind the center dash panel under stereo. Check out ramforum.com there are a few guys on there who have added it

You might as well just put hydraulic brakes on your trailer, it essentially does exactly the same thing. Except it's a more reliable mechanical system, and not an electrical system relying on wireless and a 3 axis accelerometer. This is just a lawsuit waiting to happen.
