First, to remove the brake light switch, start by depressing and holding the brake pedal, rotate the switch counterclockwise, and remove it from the bracket. To install the switch, pull up on the brake pedal, place the switch into the bracket filling, and then lock it in place. Next, inspect the mounting bracket for the switch(s). If the speed control switch is also being removed, use the same procedure. If it has a locknut setup loosen the locknut and unscrew the switch.
