Seat Belt Switch: Description
All vehicles are equipped with a driver side seat belt switch that is a small, normally closed, single pole, single throw, leaf contact, momentary switch. The driver side seat belt switch is integral to the driver side front seat belt buckle unit (1), which is secured by a screw to the inboard side of the driver side front seat frame.
The seat belt switch is connected to the vehicle electrical system through a two-wire pigtail wire harness and connector (2) on the seat belt buckle half, which is connected to a dedicated take out and connector of the vehicle wire harness located within the driver side front seat riser.
The seat belt switch cannot be adjusted or repaired. If ineffective or damaged, the entire driver side seat belt buckle-half unit must be replaced.
