The sensor unit is positioned in a sensor bracket in the front SIPS pipe's outer end. Placement is the most protruding part of the seat against the inside of the door.

A pressure plate is mounted in front of the sensor unit. On side impact the pressure plate captures and distributes forces from the door's inner panel to the sensor unit.
