Hello Brian, thanks for reaching out. The adapters you mentioned the Dexter K58-036-01 part # T4845900 and K58-036-00 part # DX35FR will not work with the Hydrastar HBA-1600 actuator. Those are only for the Dexter Axle BrakeRite actuator.

We do carry an adapter module for the Hydrastar actuator, part # HBA-CAM. This helps the actuator be compatible with EOH brakes and it works on the 1600 actuators with a serial number 506100 or higher.

To be honest though, I do not have complete confidence in these adapter. There are may cases where the flat out just do not work. In these cases, the best option is the replace your brake controller with one that is compatible with EOH brakes, like the Tekonsha P3 # 90195.

What kind of actuator and brake controller are you using?

Hey Brian, did you have a chance to try the Hydrastar adapter module or consider switching to the Tekonsha P3 brake controller? I'm curious to know how it worked out for you, as it could help others facing similar compatibility issues.
