Ordered the Nissan trailer hitch when I bought the car. The parts man said that everything was included in the kit. Just a warning, The kit came in and the service department started the install and guess what? The wiring harness must be ordered seperately from the kit. Another part that must be ordered to complete the install is a section of the bumper reinforcement that must be swapped out to allow the hitch to fit under the bumper. I mention this so that you will be able to order all the parts from the beginning. I will have to go back again to have it installed after waiting three hours in the service department.
