Now this will come with and have all the necessary wiring components to a second towed vehicle. So you can use your Portable Brake Buddy System in that second vehicle.

So basically, just pop it out, and then you can plug it in, all this would be on the second vehicle, you'd be good to go. So you're gonna get included with this kit, your breakaway system. It's gonna have the built-in breakaway pin. You know if you break away, put it back in to reset it, it's gonna have that quailed lanyard with it. So nice stretchy, you got the nice two hooks on both ends.

One would hook into the breakaway pin, obviously, all the zip ties, the mounting little bracket, and hardware that you need for that guy. You're also gonna get the battery charge line hit, that's gonna be this guy here. It's gonna come with all the necessary wires and everything. It's got nice wire coatings, and heat shrink, and whatnot on it, to keep it nice and safe for you for long lasting. And then of course you got your dash mount connector, that's this big guy here.

Pretty much what everyone else says. Clean installation. The trimming is not that bad if you have the right tool. Even if you screw up the trimming a little bit it gets covered. Bolts were a little difficult but if you've done anything in your life you can do this. It kills me to see people spend big money on things like this installation.

This 1 year review is relative to the brake buddy parts only, as this was a full flat tow parts install. My only issue with the Brake Buddy portion is that the pigtail from the unit to the dashfirewall plug in doesnt seem to last. Not sure why. Have gone through two of them.

  • Easiest Setup For Flat Towing a 2024 Ford Maverick With Demco Commander Tow Bar and Brake Buddy
    As you already have the Demco Commander II Non-Binding Tow Bar # DM9511012 the Demco Tabless Base Plate # DM77YV is going to be the easiest option for your 2024 Ford Maverick, as you will not need any adapters to work with a different manufacturer base plate.
