Question:
Will this brake controller work on a 2020 ram 3500? And will it interfere with the integrated brake controller in the truck? How do you go about installing it?

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.
