HEIGHT SENSORS

Installation of height sensors is a trial-and-error process and requires patience. The goal is to
use as much of the sensor range as possible which will maximize height adjustment accuracy.
Determining Height Sensor Mounting Point
1. Choose a solid mounting point on the body or frame that will not deflect. Anything that
moves is not a good mounting point.
For best system performance, mount the sensors in the same location on the driver's and
passenger's sides of the vehicle. This will ensure that the sensor range is equal side to side.
2. The sensor can be mounted in any direction and will still work as long as the sensor
arm base's extruded point is pointing toward the connector when the sensor arm is at
its mid-position. The height sensor assembly is supplied in position A. Remove the arm
to reposition it to B or C but keep the extruded point in the direction of the connector.
The orientation of the connector must be either facing down or parallel to the ground
to avoid water accumulating on the connector and making its way into the sensor.
Also, mount the sensor where the arm will be mounted opposite or 90 degrees from
the connector wiring if possible. If not possible, ensure the wiring harness is secured
away from arm travel so it will not get caught up when the arm cycles (fig. 16).
Preferred orientations (A., B.)

As supplied
B.
Do NOT position sensor with connector up, or with point on sensor base pointed anywhere
but at the sensor connector when arm is in its mid position.
3. Find a point where the sensor will be directly above the lower linkage mounting surface.
It may be necessary in some applications to fabricate a bracket to locate sensor in
appropriate position.
4. Make sure that the sensor and sensor arm clear the vehicles suspension, wheels, and
any other moving parts. This includes steering the wheels all the way to the lock position
left and right to ensure proper clearance. Provide enough clearance to compensate for
heavy load/movement that can't be seen from manual/physical articulations.
5. Keep the sensor and wires away from heat sources and moving parts that will create
wear and may damage these components.
