[ hyjack ] I decided to wait till I got the truck to see how to hook up the connector. I am considering two options. One is to disconnect the pin plug on the bumper and purchase the cable from Dodge that plug into the truck harness and locate the 7 pin connector in the bed. If I need to use the bumper plug, I'd have to switch cables under the truck. Other option is to make a harness that plugs into the 4 pin plug at the bumper and then splice the remaing 3 wires.
