Hey Paul! You will need an EOH brake actuator, breakaway, and wiring to upgrade to EOH on your trailer. Hydrastar makes a kit that comes with everything you need so that would be the easiest way to do it. The # HS481-8065 is for drum brakes and the # HS481-8067 is for disc. You can either run bolts through your current surge brake actuator to permanently lock it out or replace it with a standard coupler like # DM15000-52.

Hey Paul, did you decide to go with the Hydrastar kit for your trailer upgrade? I'm curious to know how it worked out for you, as your experience could really help others looking to make a similar upgrade.
