Hi Dannon; do you have the factory port for a 7-way on the back of your 2012 Ram 5500? The 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, Chrysler/Dodge OEM Plug Adapter # HM40975-11933 comes with the connector and wiring harness to plug directly into your factory wiring. Your factory plug will match the square plug in the attached picture. If you have something else let me know and I'll see what is available.

Hey Dannon, did that 7- and 4-pole trailer connector and bracket fit your Ram’s factory port the way you needed? Knowing how it matched up could help others trying to find the right harness for their truck.
