Looks like your Integrated Brake Controller might not work with the new 5vers braking system. Found this article on etrailer.com
Can 2012 Dodge Ram 3500 Factory Brake Controller be Used w/Electric Over Hydraulic Trailer Brakes
Question:
i just bought a 2012 ram 3500 and my goose neck electric over hydraulic brakes are not working all the lights and turn signals work but not the brakes. the truck came with a built in break controller. i have read some forums and kind of understand why its not working. my question would be is there a way to keep my existing break controller and still be able to use my trailer breaks with out taking away the stock look of my interior?

It sounds like the factory controller and the brake actuator you have are not compatible. The factory controller in a 2010 and up Ram is not for use with electric over hydraulic systems. In order to get the brakes working, you will need to install an aftermarket trailer brake controller like the P2, # 90885.
In order to use an aftermarket controller you will need to disconnect the ITBM (factory controller) which will cause a warning light on the dash. To disconnect the ITBM, you will need to contact the Dodge Business Center to remove the sales code (XHC). Then a Dodge dealer has to reconfigure the TIPM (totally integrated power module). I have included a link to an FAQ that should help you.
Once you have these steps done you can install the brake controller using wiring harness # 3021-P. I have included some links to isntructions that will help with the remainder of the installation.
