• Demco Hydraulic Brake Actuator for Drum Brakes with Lockout
  The Lockout Solenoid Kit # DM5837 you referenced is not designed to fit the DA86 model of Demco actuators, which is the part # DM8608601 you referenced. There is an alternative option for a similar hydraulic drum brake actuator with a lockout that I recommend checking out, the Demco Hydraulic Brake Actuator w/ Manual Lockout - Drum - Zinc - 8" Adjustable Channel - 8K # DM8760011. This is just the channel portion of the coupler and I recommend adding the Demco Trailer Coupler - Adjustable...

• 5-Way Adapter Recommendation for a 2008 Mazda CX-9 For Surge Brake Trailer
  If you don't mind a little bit of wiring I have a much cheaper solution to activate your reverse lock out solenoid. You would just need the part # 47515 that will adapt the 4-way to a 5-way. Basically you just plug this into your 4-way and then wire the 5th circuit up to the reverse light circuit and the reverse lock out solenoid will activate like it should. I attached an install video for this harness for you to get an idea how it would install on your vehicle.

• Can Trailer Back Up With Demco Hydraulic Trailer Brake Actuator # 8605001 Installed
  The Demco Hydraulic Trailer Brake Actuator # 8605001 that you purchased doesn't have an electric or manual lockout integrated so to back your trailer with the actuator as-is would mean you need free-backing brakes on your trailer. You still have the option to add an electric solenoid though with part # DM5837. This installs by threading it into your master cylinder and then allows you to back your trailer up when you connect the wiring to the reverse light circuit on your tow vehicle/trailer....

• Troubleshooting Boat Trailer Brakes Locking Up in Reverse
  It sounds like your reverse lockout solenoid is not working properly. You can use the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 or the slightly better designed Demco # DM5837. You will wire one side of the solenoid to the reverse light function on your 7-way and then the other wire will be grounded to your trailer frame. I've attached a couple videos of installations to assist. I've attached a photo of the 7-way pin locations to assist.

• Best Replacement Reverse Lockout Solenoid for Demco Hydraulic Brake Actuator # DM8509612
  We do have a replacement reverse lockout solenoid for the Demco Hydraulic Brake Actuator # DM8509612, but the Replacement Solenoid Valve # T4748800 that you referenced is not designed and has not been tested to fit the Demco actuators. Instead you will want part # DM11993 for just the solenoid or part # DM5837 for the kit that includes the solenoid cover. These are designed specifically for the Actuator # DM8509612. I have attached a link to an installation video of this solenoid...

• Adding Trailer Brake Controller Wiring to 7-Way Connector
  For your 7-way wiring you will want to simply use kit # 5506 to give you the circuit breakers and wire you need for your brake controller and 12V power. This will give you the replacement wiring you lost from your # ETBC7 kit. If you don't already have a brake controller, I recommend the Prodigy P3 # 90195. I personally think this is one of the best on the market. I've attached a video to assist.
