Thank you for all of the info!

The Curt Echo Wireless Trailer Brake Controller # C51180 just requires the trailer lights and 12V power pin to operate properly but the Curt Echo Under-Dash Trailer Brake Controller # C27JR and Custom Wiring Adapter # C51392 require your 2020 Honda Ridgeline to have the tow package so all of the wiring exists on your 7-Way - especially the brake control pin in the 5 o'clock position (see attached).

If you grab a tester and put it on that pin and then apply the Curt Echo brakes manually you should see power on this pin. If you don't then something is going on with the wiring from the controller back to the 7-Way on your Ridgeline and you need to look for any damage or disconnected pieces.

If you do get power on that pin then the issue is somewhere on your trailer and you'll want to check your connectors and wiring to make sure everything is properly secured and in good condition.
