The stoplamp switch is mounted on the brake pedal bracket and is connected to the vehicle harness via a 4 pin multi plug.

When the brake pedal is pressed, the switch contacts close allowing a hard wired signal feed to be sent to the ECM. A stoplamp switch status message is then sent from the ECM to the ABS module on the high speed CAN bus.
