Sorry, I did not make myself clear. The dealer threw in the Class II hitch and wiring kit from the Lincoln Accessories web site. I will be installing it myself. I will not have the upgraded battery, oil cooler, larger radiator and fans. My towing capacity will be limited, as stated in the owner's manual. No problem for what I will be towing.
The hitch and wiring kit arrived Friday with no instructions. There was a reference to a dealer-only web site for installation instructions on the wiring box. The parts man printed those out for me. Problem: He ordered the correct wiring kit, but had only ordered the replacement bumper/hitch unit rather than the hitch kit. He claimed it was correct, but the part number said otherwise. The salesperson took care of the problem and the hitch kit has been ordered. It includes the bumper/hitch and appropriate fasteners/hardware.
The wiring kit is spliced into the wiring harness at several places inside the cargo area. There is one power wire which must be run to the main electrical distribution box in the engine compartment.
