Safety Belt Warning Indicator
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The safety belt warning indicator is powered through the instrument cluster and is grounded through the safety belt retractor switch. When the safety belt is extended, indicating a buckled condition, the switch will open to the instrument cluster and the safety belt indicator is extinguished. When the safety belt is retracted, indicating an unbuckled condition, the switch closes and provides a ground to the instrument cluster and the safety belt indicator is illuminated.
