I went to settings and selected ‘light electric trailer brakes’, then set the gain at about 5 to start. But when I braked to test it, there’s no way indication of that on the dash. Am I missing something?

Did you have a trailer connected? The brake pedal only works with the trailer connected. You can squeeze the levers without a trailer connected and they will move the dash gauge.

Yes. When I said I was testing it, I meant braking and seeing if the trailer was braking enough and not too much. But I’m seeing nothing on the dash.
