1. Determine which channel on the CRVW3 will be used for each sensor.
2. Unscrew and remove the connector on the outside of the enclosure that corresponds to
the channel currently being installed.
3. Remove the capping pin.
4. Feed the removed connector over the bare wires on the end of the sensor cable, and
position the connector a few inches down the cable.
5. Feed the wires and cable through the connector hole.
