Use of Trailer Brakes (tekonsha voyager)

I have a voyager. It took me a while to get it set right, but it is a proportional controller. The harder you brake, the redder the led. Before I got it set right, it was very grabby in slow traffic. Bugged my wife to no end.

Too much gain on the trailer brakes will have the trailer doing more than its fair share of braking. You also get the jerking. Too little and the TV brakes work too hard.
