SYSTEM INFORMATION

WirelessAIR is designed for automatic digital leveling of the on-board compressor system. The kit includes a compressor, manifold, wiring harness, and wireless digital controller. The system can be used in or outside the vehicle, for adjustments in full view of the vehicle.

The wireless digital controller is a compact, battery powered unit. It also includes a clip that can be attached to the vehicle’s visor. Three user-defined memory settings are provided for frequently used settings. As an added safety measure, minimum air pressures are automatically maintained. The manifold is also weather resistant for maximum life expectancy.

IMPORTANT SAFETY NOTICE

The installation of this kit does not alter the Gross Vehicle Weight Rating (GVWR) or payload of the vehicle. Check your vehicle’s owner’s manual and do not exceed the maximum load listed for your vehicle.

Gross Vehicle Weight Rating: The maximum allowable weight of the fully loaded vehicle (including passengers and cargo). This number — along with other weight limits, as well as tire, rim size and inflation pressure data — is shown on the vehicle’s Safety Compliance Certification Label.

Payload: The combined, maximum allowable weight of cargo and passengers that the truck is designed to carry. Payload is GVWR minus the Base Curb Weight.

RECOMMENDED COMPRESSOR LOCATIONS 

Important

LOCATE COMPRESSOR IN DRY, PROTECTED AREA ON VEHICLE. DIRECT SPLASH OR EXCESSIVE MOISTURE CAN DAMAGE THE COMPRESSOR AND CAUSE SYSTEM FAILURE.

Disclaimer: If you choose to mount the compressor outside the vehicle please keep in mind the compressor body must be shielded from direct splash and the intake should be snorkeled inside the vehicle. If the compressor does not include a remote mount air filter or if mounting the compressor outside the vehicle, make sure to orient the compressor intake filter so that all moisture can easily drain.

Please also remember...

• To avoid high heat environments (including engine bay and exhaust)

• The compressor can be mounted in any position — vertical, upside down, sideways, etc.

• Compressors ingest moisture and will deposit water inside the system. In sub 0˚F environments this water may freeze and require the addition of air brake antifreeze (see page 18).

INSTALLING THE COMPRESSOR

1. Select a rigid mounting location for the compressor on the vehicles frame or cross member (fig. 1) that shields the compressor from the elements and heat sources.

NOTE: The electrical harness will force the compressor to be within 24” of the manifold in order to make electrical connections.

2. Use the supplied compressor fasteners to fasten the compressor to the frame or cross member.

3. Use the supplied self tap fasteners (V) if installing on a boxed frame.
• One of the screws will be used as an electrical ground for the compressor terminal.
• Another of the screws can be used to mount the compressor relay.

INSTALLING THE MANIFOLD

1. Select a rigid mounting location for the manifold (A) on the vehicles frame or cross member that shields the manifold from the elements and heat sources (fig. 1).

2. Use mounting bracket 11027 (I) to secure to the rigid mounting surface with a 17173 fastener (J). Please refer to the “Manifold Mounting” diagram.

NOTE: Locate manifold above compressor if possible.
Some vehicles have high radio/electronic interference, and require manifold to be mounted close to driver. 

INSTALLING THE HARNESS

1. Connect electrical connector to manifold (A). a. Push down till fully seated. b. Push red secondary lock down.

2. Connect compressor to harness.

a. Cut off terminal on compressor red wire.
b. Strip ¼” insulation off compressor red wire.

d. Crimp on weather proof blue butt splice (L) to harness wire pink wire AL007 (PK- 14GA).
e. Heat buttsplice to seal connection.
f. Connect compressor ground wire ring terminal and relay to vehicle ground (fig. 1).
• Using one of the self tapping screws for the compressor you can attach all the components to the vehicle frame ground.
g. Connect the black wire “ground to battery” to the negative battery terminal.

NOTE: This system is designed to pass current through the frame ground back to the battery negative terminal. To ensure proper system operation ground circuit resistance should be kept to a minimum.

3. Connect the AL004 circuit to the vehicle ignition.

a. Route the AL004 (RD-10GA) wire to a 15A ignition source.
• Cut off the excess wire length if all is not needed.
b. Strip off ¼’ insulation off both sides of the inline fuse holder (N) and the AL004 (RD- 10GA) wire.
c. Crimp on the weather proof yellow butt splice (M) to AL004 (RD-10GA) wire.
d. Crimp on the weather proof yellow butt splice (M) to one side of the inline fuse holder. • Heat buttsplice to seal connection.
e. Select the appropriate type of fuse tap in terminal for your application (fig. 1).
f. Crimp on the correct terminal that mates with the appropriate type of fuse tap in terminal for your application (P or Q).
g. Connect the terminal to the inline fuse holder (N). h. Install fuse (O).

ATTACHING THE AIR LINES

1. Manifold to Compressor
a. Cut a section of DOT ¼” hose (H) to the necessary length to reach from the compressor leader hose to the manifold port “C”. (fig. 4)
