If you wanted to install an electric reverse lockout on the DA10 Demco actuator part # DM8102222 you would want the part # DM11993. This is confirmed to fit DA10 actuators like this. When this solenoid has power on it would prevent hydraulic pressure from building in your brake lines and assemblies.

The Demco #DM72VR you installed is not designed to have any sort of manual lockout or bolt to hold it together, so I would not recommend doing that as you could potentially damage the coupler and render it unusable. The better option is installing a…

The reverse lockout solenoids stop brake fluid from being released from the master cylinder and sent to the wheel cylinder. It does this by receiving an electric signal, usually from the reverse light circuit. That said, if you were to wire this into…

You could get the Demco lockout solenoid #DM5404 to fit the UFP coupler. But as far as whether or not it is the right type of solenoid is what you need to look at. This one is designed to route brake fluid back into the master cylinder via a second…

Answer 8

This likely means your hydraulic brake actuator does not have a reverse lockout. Reversing the trailer up an incline compresses the actuator and activates the brakes. Adding a lockout allows you to backup without actuating the brakes. We have the…

Answer 10

An electric reverse lockout solenoid like #T4748800 from Titan and #DM11993 from Demco does have two pigtail leads. These leads are non-polarized, so either wire can be used as ground or hot. We are not familiar with any single-wire self-grounding…
