The Towing Wire Harness is designed to be used with Tow Hitch Receiver.

Before towing, confirm your vehicle and trailer are compatible, hooked up and loaded properly and that you have any necessary additional equipment. Do not exceed any Weight Ratings and follow all instructions in your Owner’s Manual. The maximum you can tow depends on base curb weight plus the total weight of any cargo, occupants, and added vehicle equipment. “Added vehicle equipment” includes additional standard/optional equipment and accessories added by the manufacturer, dealers, and/or vehicle owners. The only way to be certain of your vehicle’s exact curb weight is to weigh your vehicle without passengers or cargo. [Calculated with the new SAE J2807 method.] Installation of a tow hitch receiver or other accessories located near the rear bumper may require disabling or removing the kick sensor, and the sensor operation setting in your vehicle should be turned off. See Owner’s Manual for limitations.
