You do not need the Mopar tow bar wiring harness anymore for the 2019 Jeep Cherokees like your Trailhawk Elite thankfully. At one point the harness was needed to prevent steering issues when flat towing but Mopar has fixed the issue on your vehicle currently.

What you will need is a base plate kit confirmed as a fit for your vehicle like the Roadmaster part # RM-521451-5.

In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon All Terrain, # RM-522. This has non-binding arms which makes the setup very easy to connect/disconnect.

For lighting/safety cables, locks, and covers for the tow bar we have the Roadmaster Falcon All Terrain kit part # RM-9243-1 which comes with all of that as one part number. The diode kit that comes with this allows you to splice into the taillight wiring so that your RV controls the vehicle taillights and does not require drilling into the taillight housings. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV.

And finally, most states now require supplemental braking in the vehicle being flat towed. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles.

Most likely you will also need a high low adapter so that the tow bar will be level when you are flat towing. I attached a link to a page that has all of the ones we carry.

I have included a couple of helpful links to our articles on flat towing for you. Be sure to consult the vehicle owners manual for more specific information on flat towing your vehicle.
