How To Add Reverse Lockout To Demco Hydraulic Trailer Brake Actuator 8605001


Need to know what else to order to make it a lock out hitch. We have a Rinker Cuddy that weighs approximately 5000 pounds including the trailer. We didnt notice that it was a no lock out. Want to purchase items to correct. The hitch is installed, no problem. Please advise.

To add reverse lockout to the Demco Hydraulic Trailer Brake Actuator - Drum Brakes - Zinc Plated - 2" Ball - 6,000 lbs 8605001 you purchased you will need the Reverse Lockout Solenoid Kit for Demco DA66B Hydraulic Brake Actuators - Non-Bypass # DM5836.

One wire from the # DM5836 will get grounded, and the other will get attached to a 5-way connector on your trailer. If you do not have a 5-way connector on your trailer currently you will need to add one using # HM37918.

Once the trailer side is done, you will need to add a 5-way connector to your tow vehicle using the Curt Trailer Connector Adapter - 4-Way Flat to 5-Way Flat - Vehicle End # C57187 which will plug into your 4-way connector. You will need to splice the blue wire into the reverse light circuit of your tow vehicle, using a circuit tester like # PTW2993 will help you identify the correct wire.

This system works by sending a signal to the lockout solenoid when the reverse lights are on, allowing you to back up your trailer without applying the brakes.

I included videos of the products mentioned for you to take a look at.
