as far as wiring. does it need to be inside the bed of the truck or can you hook it up on the bumper?
If you already have a 7 wire connector on your bumper then yes it will work since its all the same wiring. However, this would mean the cable would have to go up and over your tailgate and may not be long enough especially in turns.
My truck already had a factory 7 pin connector on the bumper. The shop that installed my hitch added a cable and new connector to the bed of the truck. It was an easy install that simply T'd off the existing connector harness to the bed. They charged me $90 for parts and labor.
