Hey Charles, did you verify that the serial number on your actuator is one that is listed as compatible? There are certain serial numbers this works with and does not. Based off your vehicle this is the right adapter for that, but there may be an issue with the model actuator you have.

We installed the CAM into our 2018 Ram 5500 Laramie. Normally we have seen these devices installed in the trailer near the hydraulic brake actuator. We decided that installing it in our truck, we could tow other trailers that had disc brakes too. We just put a small toggle switch inline to be able to add or remove the CAM to the 5500 brake circuit. We just turn the CAM off when we are not hooked up. This arrangement and part works perfectly. The design of the CAM allowed for a very neat and easy installation. Excellent product one year in use.

My Carlyle hydraulic system was installed on my 2008 Silverado HD 3500 dually by MOR-RYDE. The brake system would not connect to the truck when the truck was started. We discovered that if we turned the key ON, without starting the truck, that the TRAILER CONNECTED message came on the DIC. Then, the truck could be started and the brakes operational.Recently, we can no longer connect the brake system using the above method and I have no trailer brakes. When the key is turned ON, the HBA-CAM Actuator unit makes a click sound, but does not activate the brake system.

This fixed our problems with our 2013 dodge and horse trailer. Acuator was trying to run all the time before we installed it

Yes, that is correct Brett. It is listed above "# HYD29ZR (sold separately) is needed for 2024 - 2026 GMC or Chevrolet models with factory brake controllers." I am glad you were able to get it figured out.
