Or are we talking about even the brake wire (signal) being wireless?

It does. If the phone disconnects it keeps the last settings. The software has trailer profiles you set for each trailer and then when you turn it on you choose the profile. Or you can adjust to whatever settings you want. And it just keeps the last setting whenever you lose phone connection or you unplug/turn off the vehicle. For the most part you can setup and then disconnect for the rest of the trip. They also have a wireless dash mount module if you want a manual switch to use mounted on the dash separate from the phone.
The biggest issue I've read about is that Ford 7 pins don't keep the 12+ pin hot all the time like everyone else. So for whatever reason the Fords cut the 12v pin power from time to time and then it won't work. Not sure what the logic is for Ford doing that, but there's a list of model years that are not compatible with Ford vehicles. My guess is that it's where most of the issues are from.
Otherwise there's no reason why it would be less reliable than the same parts being in the dash vs in the plug. It's the same stuff doing the same things. Just in a different spot.
