1.Choose a flat place near air compressors to install relays.

2.Drill holes and install bracket(Fig.5-1).

Fig.(5-1)

6.Install Height sensor Notes: For the installation of the height sensor, you need to watch the movement of the suspension under the car, this process should be completed with the help of jack. Fig.6-1 shows the distance of some points of the suspension arm when it moves up and down. The distance can't be too near or far away from the point O. "A" is very near rotation point O, then it almost has no space to move, "B" is far away from point O, it has enough space to move, but it may damage height sensor or linkage(Fig.6-2).

1.Find a desirable mounting point (name as"X") at the suspension, use it as the datumpoint in the following measurement(Fig.6-3).

2.Draw a comma at a corresponding place of the suspension arm under X(It will be the mounting location for the bolt of the linkage).

3.Rise the vehicle to the highest position, name the distance from X to the comma as A(Fig.6-4).

4.Lower the car to the lowest point, name the distance from X to the comma as B(Fig.6-5).The distance of the sensor movement is A minus B(Fig.6-5).

5.If the movement distance is shorter than 120mm,then move the two points (X and the comma) a little far away from the rotation point of the suspension arm, repeat step 1, step 2 and step 3. Ifthe movement distance is longer than 120mm, then move the two points a little nearer to the rotation point of suspension arm, repeat step 1,step 2 and step 3. It' s hard to adjust the distance to 120mm accuratly, keep the distance below 120mm,not above 120mm(Fig.6-6).
