I use the BlueOx Patriot, which is essentially a Brake Buddy, in my 2009 Jeep Wrangler X.. Not the same as your Cherokee, but pretty close. I've been happy with it. I sometimes loose the connection between the remote (in RV driver's area) and the box, which delivers a beep and "C" signal, but the brake system still works regardless. You don't even need that remote for it to work, though it's nice to have a visual on it. Can't determine why on some days it has no issues connecting, and other days it struggles. Ultimately, it works, so I'm not concerned.
