The switch has 1 connector pin.

The switch is chassis-grounded and receives a B+ power supply via integrated BCM resistance of 1.5kO. The control module input is digital; voltage above 2V is determined to be an open circuit and lower than 2V is determined to be closed.

See connection to the BCM in DICE .
