SUPER DUTY ONBOARD AIR SYSTEM

DASH PANEL GAUGE INSTALLATION (USE CONTENTS OF PARTS PACKAGE #4)

Your VIAIR Onboard Air System comes complete with a Dash Panel Gauge to monitor the pressure of your

2.0 gallon VIAIR air tank. Additionally, the Dash Panel Gauge has an ON/OFF switch preinstalled that will

allow you to turn the system off by cutting power to the pressure switch with relay that you have already

installed. We recommend that you install a master ON/OFF switch to allow the system to be turned off any

time you anticipate leaving the vehicle parked for any length of time, and to avoid draining the vehicle’s battery

unnecessarily due to a slow air leak in your system. (See Figure 3 on back of manual)

IMPORTANT: Each Dash Panel Gauge has been tested and calibrated. The air inlet on this gauge has a factory

installed compression tting. DO NOT attempt to tighten or loosen the body of this compression tting.

Any adjustments will cause the gauge to malfunction and void warranty. The Dash Panel Gauge included in

this kit is rated for 150 PSI. Do not pressurize gauge over 150 PSI.

1. Select Mounting Location for Dash Panel Gauge:

Select a mounting location with a rigid mounting surface such as the bottom edge of the dashboard.

Use the gauge mounting panel as a template; mark off two mounting points to be drilled.

Carefully drill two 13/64” diameter holes as marked. Do not mount Dash Panel Gauge at this time.

2. Air Line Connection to Dash Panel Gauge:

Remove only the collar of the compression tting from the back of the Dash Panel Gauge. Do not loosen of

tighten the body of the compression tting, which is permanently afxed to the air inlet of the gauge. Insert air

line tubing through this collar, and then push air line tubing onto the barb of the compression tting until the air

line completely covers the barb. Tighten collar onto the body of the compression tting with a wrench.

3. Routing Air Line to Air Source:

Route the air line tubing on the Dash Panel Gauge to the air source. Do not cut air line yet. In some cases a

hole may need to be drilled to enable the air line to pass through to the air source. Make sure that the air line

tubing is protected from any sharp edges of the drilled hole using grommet strip supplied. Connect to the tank

using the 1/4” compression tting supplied.

Installation Tips:

- When cutting air line tubing, always cut as squarely as possible. Use a hose cutter or razor blade.

- When routing air line tubing, always remember to avoid sharp edges, heat sources and tight bends.

(Air line must be routed at least 12 inches from exhaust systems & other heat sources.)

IMPORTANT - Drilling through rewall:

Always be sure of what is on the other side of the rewall before drilling.

Take care not to damage your vehicle’s electronic systems or components.

4. Wiring the ON/OFF Switch:

Attach one of the two remaining female terminal connectors to the wire that was routed from the pressure

switch trigger wire (Small Red Wire on pressure switch with relay) There are two male spade connectors on

the back of the ON/OFF switch. Connect this female terminal connector to one of the male spade connector

on the ON/OFF switch. Next, attach appropriate size ring terminal provided in the kit to the end of the wire

with the Inline Fuse. (The ring terminal should be about 12” from the inline fuse.) This wire is referred to as the

power wire. Temporarily position the ring terminal at the power source and route power wire to the dash panel

gauge, measure and cut to appropriate length. (If additional wire is necessary, use 16 AWG wire.) Attach the

remaining female terminal connector to end of power wire, and connect to male spade connector on the

ON/OFF switch. (Note: Do not connect gauge to power source at this time.)

5. Wiring the Dash Panel Gauge for Illumination:

There are two wires, one red and one black connected to the light bulb of the gauge. Connect the red wire

to a suitable fused dash panel circuit. Use the quick splice connector included in the kit for wire connections.

The black wire is to be connected to a suitable ground source.

6. Mounting the Dash Panel Gauge:

With all electrical and air line tubing routed and connected properly, mount the dash panel gauge using the two

13/64” nuts, bolts, and washers included with the Dash Panel Gauge. Make sure that no electrical wires or air

line can be contacted by vehicle pedal operation, or by use of any safety equipment. Use provided zip ties to

secure air line and electrical wiring.
