Expert Reply:

The Curt TriFlex Trailer Brake Controller part # C51140 is a fit for a 2020 Ram 3500 when used with the Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51458 but you must take the truck to the dealer to have them flash the PCM. It will plug into a factory port under the dash.

If you don't want to worry about flashing the PCM you can use the Curt Echo Wireless Trailer Brake Controller part # C51180 which is plug and play and overrides the factory signal.
