Hi Brian! Yes, the Hydrastar Marine Electric Over Hydraulic Actuator for Disc Brakes # HS381-8067 is compatible with the OEM brake controller on your 2025 Ram 1500. The brake actuator works with Ram trucks 2010-Current. See the attached chart.

What are you towing with your Ram?

We have installed many of these hydraulic pumps, and they do seem to work well with the Dodge Ram; however, as indicated in the chart above, some of the Fords and some of the GM Chevrolets don't "like" them, I guess. They keep indicating that the trailer is not connected, so it will not operate the brakes. As a workaround, we have actually installed a common brake magnet from an electric brake in line between the truck and the pump to sort of "fool" the truck into thinking it is connected to the trailer. (We just zip strapped the trailer brake magnet to the frame somewhere and wired it into the blue wire. ) This seems to have fixed the problem, (temporarily) until you can buy the CAM adapter that's needed.

@Paul what you're describing is the same concept as the # HBA-CAM. Putting a magnet inline like that was a pretty common workaround for a while and does the job in a pinch. The adapter module is definitely the better long term solution since it's designed specifically for this application. Thanks for sharing your experience!
