The dealership is correct in a sense. Even though your 2014 Jeep Grand Cherokee has the factory tow package wiring, the wiring may not be activated. You may have to take the vehicle to the dealership so they can program the computer to activate the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector Item # C55515. Should only take about 10 minutes. It is not uncommon on some vehicles that have factory tow package wiring and it not be activated. As far as a code needed, I haven't heard that. If there is a code needed it should come from the dealership for the computer on your vehicle. They should be able to obtain that information from your VIN #.
