When flat towing and Jeep Grand Wagoneer is set in neutral to tow. Will setting it to tow mode will it break with a cable hooked to the brake pedal? Can't seem to find information on how to set up breaking. I had an Air Force one connected to the 2018 Grand Cherokee but it had an old style brake booster. This one is electronic and it does have the flat tow neutral button just behind the shifter.
