Ground Speed Signal Connector
Some implement electronic controls use the signal from the ground speed sensor. Implements that require the signal can use the four-pin connector. The connector is located below the service brake pedal behind the floormat. This connection functions only if the ground speed sensor is installed.

Some monitors from a OEM manufacturer only require the connection of pin 1 and of pin 2. You may need to disconnect pin 3 and pin 4 in order for these monitors to function properly. The machine's ground speed sensor is powered. Therefore, pin 3 is connected to pin 4 so that the ground speed sensor appears to be functioning to the monitor from the OEM manufacturer.
Note: An extension harness is available. Consult any Caterpillar dealer.
