The reason I mentioned “adjustable” voltage is because the brake controler will have a thumb wheel or knob to increase or decrease the voltage to fine tune the braking force of the trailer.
I'm pretty sure it's not an electric brake control. However I don't know what it is, so its possible. It may not be for brakes at all now that I'm typing this.
I think there were 2 knobs (not for sure) but one definitely said Boost.
I was curious if it was a control for a toad brake system or some type of boost control for the onboard hydraulic brake system. But it could be for something else.
Any other thoughts? Anyone?
