WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The stoplamp switch is located on the brake pedal assembly. Voltage is supplied to the rear lamps and high mounted stoplamp when the brake pedal is applied.
