Wrapping up the thread.
Install a button onto the brake pedal just off to the left side w 12v on one terminal and the TR6 orange wire onto the other terminal.
Then install a potentiometer/dial onto the dash/wherevers best w the TR6 gray wire onto one of the outside terminals and a GND wire to the center terminal of the dial.
