Expert Reply:
We have either the Replacement Master Cylinder # 5672 or Replacement Master Cylinder w/ Bypass Electric Lockout # DM5918 which will fit the Demco Hydraulic Brake Actuator # DM8759933. While this actuator does have the manual lockout you can install the master cylinder with electric lockout which will save you from having to get out of your vehicle to lockout the brakes. This will use a signal from the reverse circuit which if your trailer has a 4-way you will need a 5-Way # HM37908 to replace it. You will then be able to connect to your tow vehicle using a 7-way Adapter # A75TB or if you only have a 4-way flat we have the Adapter # C57187 which will allow you to splice into the reverse wire on your tow vehicle.
