Difference Between Hydrastar Electric Over Hydraulic Kits HS481-8067 and HS381-9067  

What we have found is the integrated trailer brake controllers on trucks can be very temperamental when used with electric over hydraulic brakes. I do recommend using a HydraStar Electric Over Hydraulic Actuator Adapter Module #HBA-CAM with your…

All of that is not necessary. All you have to do is lock out the surge coupler so it cannot move in and out or disconnect the brake lines. By removing the old coupler you would have to remove the brake lines any way. A surge coupler can still be used…

Actually, if the latching portion of the coupler still works correctly, you can simply engage the manual lockout lever on your coupler which will prevent the coupler from compressing and trying to apply the brakes, allowing you to continue using your…

The integrated brake controllers of a 2014 Ford truck are compatible with electric over hydraulic actuators. Sounds like right now you have a surge disc brake kit and are looking for everything needed to convert it to electric over hydraulic. For…

The old version of the #HBA-CAM used 4 wires, but the product was updated awhile back and now uses only two wires as shown in the photo on the product description page. The white wire from the HBA-CAM would tap into the white ground wire and the blue…

The #HBA-CAM adapter will not interfere with the actuator working on your 2006 Dodge Ram that does not require the adapter. It basically just puts enough load on the output circuit so that the controller thinks a trailer is connected. That additional…

I will be happy to give you instructions for the older 4-wire model Control Adapter Module for HydraStar Electric-Hydraulic Brake Actuators, #HBA-CAM. I have included a picture that explains how to wire it in. Brake controller output from the 7-Way…

As you can see on the attached photo, the wiring diagram for HydraStar Adapter #HBA-CAM shows there can be a 25-40 amp circuit breaker in-line with the black wiring which goes from the battery's positive terminal to the adapter. I would stick…
