Expert Reply:
The trailer wiring harness options for a 2019 Jeep Grand Cherokee all require a battery wire to be run from the front of the vehicle to the rear. This wire is actually important as it's what carries the power for the trailer lights. If this was not present you'd have to pull power from the vehicle lights for the trailer lights and this has the potential to overload the factory circuits and create errors with the vehicle lights. I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118727 as our best and most reliable option. It simply plugs in behind the taillights on the vehicle and then requires a wire to be run from the rear of the vehicle to the front for power. It's not difficult but it does take some time so as long as you give yourself an afternoon to get this done you'll have no problems with the install. I have attached an install video below as well for assistance.
