Hey Simon, if you plug the Curt Echo Mobile brake controller part # C51180 into an active 7-way you will have the ability to control your trailer brakes from your smartphone in a perfectly legal way. Does your vehicle have a 7-way? Is the 12 volt accessory circuit active already?

Hey Simon, what did you find out about the 7-way and the 12-volt circuit on your vehicle? Once you know that, it’ll be clear if the Curt Echo will work right away or if you’ll need to activate that circuit first. Let me know what you find—I'm here if you need a hand narrowing it down.
