The sensor is connected to the STC control module with two leads. The sensor is energized with B+ on pin 2 and gives information to the STC control module on pin 3.

The sensor is affected by a metal tongue on the sixth bow mechanism. The sensor is affected when the sixth bow is locked on the LH side.
