I posted a question a few days ago about my fender clearance and three tailgate lamps not working. I find the Dodge never hooked them up. / They needed to be plugged into the harness. The harness was set up for a regular truck and they left the plug hanging which splices in for a dually. I never thought much of it until 6 months ago I saw a Ford and wondered why mine were not lit up or if the were just reflectors. I saw the bulbs and now finally got the answer. I wonder how it passed inspection the passed three years. I feel like dummy for not seeing all this sooner.
