Hello guys, I am installing a Uhaul towing kit and noticed what looks like an open 4 pin wiring harness connection under the rear passenger side plastic cover at the rear bumper. Is it possible this is a pre-fabricated wiring connection for trailer lights that I can plug right into instead of having to tap into the fixture wiring directly? If so any idea how I can find that harness kit? I cannot seem to find anything online explaining what this is. This is a 2019 Ford Edge Titanium AWD Thanks guys!
