A connector receptacle integral to the front of the OCM housing contains terminal pins that connect the sensor to the vehicle electrical system through a dedicated take out and connector of the passenger front seat wire harness. A hose nipple formation is integral to the OCM housing. A slot integral to the top of the OCM housing snaps over a blade on a stamped metal bracket riveted to the inboard upper seat track on models with the base seat. On models with the optional storage seat, the OCM housing snaps over a blade on a molded plastic stanchion integral to the forward inboard underside of the seat cushion pan.
3. Pressure Hose - Beneath the seat cushion a length of clear poly hose serves as the OCS pressure hose (4). The hose is securely clamped at one end to a hose nipple fitting that extends downward from the Seat Weight Sensor (SWS) (also known as the seat weight bladder), and at the opposite end to the hose nipple formation of the electronic pressure sensor integral to the outside of the OCM housing. The pressure sensor circuitry is internal and integral to the OCM. The pressure hose is filled with the same silicone fluid that fills the SWS.
4. Seat Cushion Foam - The passenger front seat cushion foam (1) is an integral part of the factory-calibrated OCS. There are two unique foam configurations: one for the standard passenger front seat and another for the optional storage front seat. The storage front seat includes a small storage bin which is accessed by lifting the center insert of the seat cushion.
5. Seat Weight Sensor - The Seat Weight Sensor (SWS) (also known as the seat weight bladder) is sandwiched between the seat cushion springs and the seat cushion foam. A heavy jute-like insulator pad (2) is installed between the lower surface of the bladder (5) and the seat cushion pan and springs. The bladder and pad are secured near the forward end to the seat cushion pan by two plastic push-in fasteners. There are two unique bladder configurations: one for the standard passenger front seat and another for the optional storage front seat. The storage front seat includes a small storage bin which is accessed by lifting the center insert of the seat cushion. The bladder consists of two sheets of an elastomeric material and a molded plastic hose nipple fitting. The two sheets of elastomeric material are sealed together around their perimeter and joined at numerous specific intervals within their field. The hose nipple fitting is sealed to a small round hole in the lower surface of the bladder and is pointed downward where it passes through a clearance hole in the insulator pad and extends to just below the seat cushion springs. The bladder is filled with a silicone fluid to become a pliable, quilted, resistive mat and is connected to a pressure hose that connects it to the electronic pressure sensor within the OCM unit.

Active Head Restraint (AHR) units (1) are standard equipment for both front seating positions in this vehicle. One inertia-activated AHR unit is located atop each front seat back. Outwardly, an inertia-activated AHR appears the same as a non-active head restraint. The mechanical components (2) that articulate the inertia-activated AHR headrest pad are all concealed within the front seat back frame assembly.

At the top of the seat back frame are two stamped steel headrest guide tubes. The guide tubes are each inserted through a molded plastic fulcrum bushing installed in the upper seat back frame member and are permanently fixed to a movable stamped steel armature bracket located just below the upper frame member near the top of the seat back. The armature bracket is secured to a stamped steel pivot link at each side that pivots on a screw threaded into a mounting bracket welded to each side member of the seat back frame.

The pivot links are each have a spring attached to a lever opposite the armature bracket attachment that is anchored to the seat back frame side member below, which provides the spring-loaded return action of the inertia mechanism. The upper end of the static lumbar assembly is secured at each side to the base of the armature bracket. Each side of the lower end of the lumbar assembly is engaged in a ramp bracket riveted to the lower seat back frame member.

The inertia-activated AHR linkage cannot be repaired. If damaged or ineffective, it must be replaced as a unit with a new seat back frame assembly.

Both the driver and passenger front seat belt switches for this vehicle are actually Hall Effect-type sensors. These sensors consist of a fixed-position, Hall Effect Integrated Circuit (IC) chip and a small permanent magnet that are integral to the front seat belt buckles (1). The front seat belt buckles are located on a molded plastic scabbard and secured by a screw to a bracket near the back of the upper, inboard seat adjuster track. The front seat belt switches are connected to the vehicle electrical system through a two-lead pigtail wire and connector (2) on the front seat belt buckle-half, which is connected to a wire harness connector and take out of the seat wire harness. A one kilohm diagnostic resistor is connected in parallel with the IC where the two pigtail wire leads connect to the IC pins.

The front seat belt switches cannot be adjusted or repaired and, if ineffective or damaged, the entire front seat belt buckle-half unit must be replaced.
