Re: Module update
While the vehicle has the wiring harness back to behind the rear bumper from the factory, it's not activated in the computer. In order for you to have power available for trailer lights (and brakes if applicable with an add-on brake controller), you need to have the dealer service department "turn on" the wiring...which unfortunately comes with a fee.
Please note that adding a hitch to your vehicle does not provide the same towing limits as the factory tow option because that option includes a lot of other accommodations to improve towing performance. The manual states Jeep will only authorize 3500 lbs with an aftermarket hitch install, including the OEM unit. I only mention this in case you intend to do some serious towing and if so, you'll need a different vehicle.
