The seat adjuster switch is supplied a 12-volt reference circuit by the driver seat module. When a seat adjuster switch is pressed the signal circuit is closed to the 12-volt reference circuit. Closing the signal circuit to the 12-volt reference circuit pulls the signal circuit high indicating to the driver seat module the switch status is active.
