HEAVY DUTY ONBOARD AIR SYSTEM

DASH PANEL GAUGE INSTALLATION (CONT’D)

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.

7. Connect to Power Source:

Before connecting the power wire to a power source, check to make sure that the ON/OFF switch on  

the dash panel gauge is in the OFF position. Connect the ring terminal of the power wire to power source.  

(This is the wire described in Step 4, which is connected to the ON/OFF switch of the dash panel gauge.)

8. Testing Your Onboard Air System:

Your Onboard Air System installation is now complete. Run the compressor to build pressure in the air tank. 

When air pressure reaches the pressure switch cut out pressure, the compressor will shut off. Inspect all air 

line connections for leaks with soap and water solution and spray with a spray bottle onto connections  

to check for leaks. If leaks are detected, air line may not be cut squarely or pushed all the way in.  

Fix connections as needed. Periodically check your system’s fitting in this manner should your compressor 

turn on more often than normal without frequent air use.
