connects to the hydraulic driver box in the “SPEED
SENSOR” position. The other end with the AMP
connector attaches to the flowmeter.
The connections for the foam flowmeter used on the
3300 system are shown in Fig 9-10. The 3-pin molded
end connects to the hydraulic driver box in the
“SPEED SENSOR” position. The other end with the
