Parts Needed to Flat Tow 2016 Jeep Cherokee Trailhawk


Im currency looking at a 2016 Jeep Trailhawk 4X4 to flat tow behind a motorhome. The used car dealer told me that these vehicles are prone to experiencing death wobbleinch if not retrofitted with a wiring harness from Fiat Chrysler? Before I buy the vehicle and the base plate, tow bar, etc., I would like to know if anyone at etrailer has any input on this?

There is a Mopar-only harness that you'll need to flat tow your 2016 Jeep Trailhawk. It recently got pulled from the market and the last we heard is they are working on a new part number to replace it (as of April 2018). It used to be part number 68321424AB though. If you check direcly with Mopar they'll be able to give you the status on the harness.

For a base plate kit you'll want the part # RM-521446-5 which is a confirmed fit and will work well.

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 2, # RM-520. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground.

For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. 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 # BRK2019, 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.
