I am not seeing a plug and play brake controller option for your 2021 Holiday Rambler Admiral on a Ford F-53 chassis. There are brake controller options like the Tekonsha Prodigy P2 Trailer Brake Controller # 90885 which provides a proportional controller with an easy to read blue LED display. But it needs to be spliced in.

I looked this up by the chassis information and the motorhome information and both indicated there is not a plug and play option available. If your motorhome has a port (plug) under the dash, please send in a picture of the connector, I would like to take a look and see if we have something that matches up but isn't listed. If you do not see a port, you have to splice in.

You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit…
