Expert Reply:
Hi Donald; the wiring harness that comes with the Curt Echo Under-Dash Bluetooth Brake Controller # C46GV is the Curt Custom Wiring Adapter for Trailer Brake Controllers # C51446. This will allow you to plug your existing Echo into the brake controller port on your 2025 Ram 1500.
What are you towing once you get the brake controller installed?

Thank you, for that response, I currently have the #C51457 pigtail connected to the controller. As soon as I get this setup completed I will be towing multiple different trailers from our camper, livestock, and Carmate Box trailers.
