Page 11: Wiring Diagram
WIRING DIAGRAM Feed two 10-gauge wires, one white and one black, from the mounted brake controller to the battery area. Using a ring terminal, connect the black wire to the 'AUX' side of the 30-amp circuit breaker. Leave the white wire to be connected later. Using a 10 / 12-gauge butt connector, attach the black wire from the 'AUX' side of the 30-amp circuit breaker to the brake controller's black wire. - Page 12 NOTE: Brake light switch connection on Ford vehicles including the Mercury Mountaineer, do not connect to the red wire with a green stripe. Connect to the light-green wire only. For vehicles other than 1989-1991 Ford E- and F-Series trucks and vans with anti-lock brakes, use a test probe to determine which wire on the tow vehicle's stoplight switch is only 'hot' when the pedal is pressed.
- Page 13 SETUP Once all electrical connections are complete and the controller display is functioning, while parked on a level surface, plug the trailer's electrical connector into the tow vehicle's plug. Connecting the trailer initiates the mounting position calibration mode. The CURT logo with a progress bar may be seen on the display followed by either 'Connected' or 'Not Connected'.
