SYSTEM COMPONENTS Wire Harness All necessary electrical wires and connectors have been included with this kit. Review Figure 1 before beginning installation. You will have to put the major components in a position so that the wire harness will reach all of them. Route the wire harness loosely throughout the vehicle as indicated in Figure 1. Each end of the wire harness is marked with the major component that it will connect with. Route the wire harness loosely throughout the vehicle as indicated

SYSTEM COMPONENTS (cont.) Height Sensors M5 Nylon Lock The height sensor connections must go to their corresponding corners for proper sensor operation. THE HEIGHT Nut (8) SENSORS AND THE WIRE HARNESS CONNECTIONS ARE LOCATION AND POSITION SENSITIVE. The sensor connectors are laid out so they work with the sensors mounted on the outside of the frame rail, with the arms pointed M5 x 8mm toward the rear of the vehicle. If the height sensors are mounted inside of the frame rail, the arms must point

SYSTEM COMPONENTS (cont.) Air Dryer Select a location to mount the air dryer. This should be a protected location to prevent damage from flying rocks or debris and close to the valve block. Ensure that a clear access to all of the fittings on the air dryer is maintained. Height Selection Switch The height selection switch may be mounted directly in the dashboard, only if the dashboard material is 1/8” in thick- ness or less. The height selection switch is located on the wire harness, simply pull

OPERATION OF THE SYSTEM Once height programming has been completed, the system is ready for use. The height selection switch is how you will be able to select your height. The switch has two green lenses with arrows printed on them. This is the primary user interface of the air leveling system. If the switch is mounted correctly, pressing up will make the height go up and pressing down will make the height go down. When a height selection is made up or down, the lights will toggle fast during th

COMMONLY ASKED QUESTIONS What is the lifetime expectancy of the Firestone dryer? If there are no system leaks it should be for good for system life. What type of accuracy is available with our system? The height sensors that we use are capable of an accuracy of 0.67% of 1 degree. Our system with ECU programming is designed to work with 1/4 of a degree of accuracy. For comparison sake, a pneumatic leveling valve can have a dead band of approximately 3/8”. How do electronics help increase the life

COMMONLY ASKED QUESTIONS (cont.) In the WR8-760-2230 system, which port from valve block goes to & from the dryer? Each port on the valve block is labeled for the designated connector. Using the air line tubing, measure the distance from each port of the dryer back to the valve block. The air line tubing should be routed from the I.D. (inflow to dryer) port on the valve block to the in port on the dryer. The next air line tubing should be routed from O.D. (outflow from dryer) port on the valve b

TROUBLESHOOTING The height change works, but the WR8-760-2230 system will not level. The left-rear corner is exhausted fully. The LED height display shows the current height. The right-front valve is switched with the left-rear valve. Correct the air line connection with the corresponding air spring location and the solenoid valve connection.

TROUBLESHOOTING (cont.) The diagnostic lights on the WR8-760-2230 aftermarket IntelliRide system toggle fast as though it is attempting to change heights, and the valve block clicks trying to pass air. However no height change occurs and there is no air pressure within the reservoir tank. (1) There is a potential blockage in the air dryer. (2) The compressor connections are not sufficient. (3) The pressure sensor is not connected. The WR8-760-2230 system is locked down, with no functions. Both o
