The adapter # HBA-CAM will not work with the HBA-12 unless the serial number is 705700 or greater. So you would need to install an aftermarket controller that is compatible with electric over hydraulic trailer brakes.

I recommend using the P2 # 90885 with harness # 3023-P for a brake controller that is compatible with electric over hydraulic actuators.

When you disconnect the factory controller to install the aftermarket one it will throw an error code on the dash. To get rid of that you will need to follow some specific instructions:

To install an aftermarket brake control you will have to disconnect the ITBM. This will turn on a warning lamp on the instrument cluster. In order to disconnect the ITBM and not get the warning lamp, your local Dodge dealer will have to reconfigure the TIPM (Totally Integrated Power Module), of the truck. Once the TIPM has been reconfigured, and the ITBM has been unplugged, you can use a vehicle specific brake control harness to install the aftermarket brake control.

To disconnect the ITBM, you will need to contact Business Center to remove the sales code (XHC). The TIPM will need to be reconfigured. Once the sales code has been disabled you can disconnect the ITBM electrical connector, under the dash, without getting the warning lamp.
