Fog Lamps
WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
The fog lamps are controlled by the SJB. The SJB monitors inputs from the headlamp switch and the multifunction switch. The SJB can only turn the fog lamps on when the ignition switch is in the RUN position, the parking lamps are on and the high beams are off. When the fog lamp switch is engaged, the SJB then activates the fog lamp relay, providing power to the fog lamps.
