To be completely honest, you shouldn't even need the Hydrastar Electric Over Hydraulic Actuator Adapter Module # HBA-CAM with your 2022 Model year Chevrolet Silverado 3500. In past years there was an issue with communication that the adapter helped to solve. But according to Hydrastar the 2018 and newer models should not have that issue.

One thing you can check is to ensure that your OEM brake controller is set to "eoh". Sometime you have to go into the trailer settings to change the mode to "eoh".

If you are still having issues with it, I would consider reaching out to Chevrolet about the OEM controller to see if they have any insight as to what could be causing the issue with the OEM controller not engaging the brakes.
