rear suspension, you can simply locate the linkage a bit closer to the pivot of the 4-link arm on one of the 4-link bars. By attaching the linkage a bit

closer to the pivot of the 4-link arm, the sensor "sees" less suspension movement than if it were attached directly at the axle location. The object is

to make sure that the suspension movement does not move the sensor arm out of its range of authority as outlined in Figure 3. On an independent

front suspension, simply place the linkage somewhere inboard of the ball joint to effectively lessen the travel of the sensor. If the sensor arm

exceeds it range of authority, the IntelliRide™ system will not respond. See page 12 & 13 for diagnostic information.

Step 4

To install the height control sensor, refer to Figure 4a, 4b and 5, to

become familiar with the mounting geometry and hardware. Be

sure that the area above and below the sensor location on the axle

is clear of obstructions for the arm to move.

What direction do the height sensors need to be mounted with the

WR8-760-2230 IntelliRide system?

If provided with a wire harness the power and ground to each vehicle corner

expects the height sensor arm to be in a certain position relative to the body of

the sensor. If mounted backwards the system would act in reverse, or not at

all. The height sensors on the right side of the vehicle need to be mounted with

the arm in the 9:00 position. The height sensors on the left side of the vehicle

need to be mounted with the arm in the 3:00 position.

Why do the height sensors need to be mounted with the arms in

a certain direction?

The supplied wire harness expects the height sensor arm to be in a specific

direction relative to the body of the sensor. The system will have a fault if

positioned in any other direction.

The sensors on the passenger's side of the vehicle must have the arm facing

9:00 and the sensors on the driver's side must have the arm facing 3:00.

Reference Figure 4.

Step 5

Take the sensor under the vehicle and find a location where the

sensor may be attached to the vehicle so that the arm extends

over the suspension. The arm of the sensor must be able to travel

from full jounce to full rebound for the system to work properly.

Looking at the table below pick out a hole on the sensor arm that

will work on your suspension attachment point. The use of the

provided template will show minimum and maximum arm move-

ment as shown in Figure 3. At ride height the height sensor arm

should be as horizontal as possible.

Notice that the maximum working range of the sensor is 6", even

with the linkage placed in the fifth hole of the sensor arm. If your

suspension provides more than 6" of travel, you will have to posi-

tion the sensor so that operates within the yellow portion of the

sensor installation template. For example, if you have a 4-link type
