STEP BY STEP INSTALLATION
All of the electrical connections are matched by male-to-female push-in terminals. (Figs.
4 and 5).
1. Install the gauge panel. Select a convenient mounting location that has a sturdy rigid
surface. The bottom edge of the dash on either side of the steering wheel is a good
location. Attach the panel to the selected location with the black self-tapping screws.
2. Install the compressor unit.
a. Hold the compressor in the recommended location and use the provided silver self
tapping screws to attach the mounting brackets to the vehicle.
b. In some cases the mounting area does not provide enough room to use a drill to
drive the screws in. It may be necessary to use the mounting brackets as a template
to drill 13/64 ” holes through the frame first and then use a 7/16 ” nut driver to install
the self tapping screws.
c. For box frames: In some cases the frame section will not be wide enough to mount
the compressor legs flat to the rail. Refer to Fig. 6 in this situation.
DO NOT DRILL ANY HOLES INTO THE FRAME OR THE FLOOR BOARD BEFORE
CHECKING FOR HYDRAULIC LINES, GAS LINES, AND/OR ELECTRICAL WIRES
THAT MAY NEED TO BE MOVED ASIDE. ALSO, WHEN ATTACHING TO THE FLOOR
BOARD, IT IS IMPORTANT TO CHECK WHERE THE SCREWS PROTRUDE THROUGH
THE FLOOR BOARD. IT MAY BE NECESSARY TO TRIM OR COVER THE TOP OF THE
SCREWS INSIDE THE VEHICLE. A SEALER SHOULD BE USED AROUND THE SCREW
TO PREVENT THE ELEMENTS FROM ENTERING THE CAB AREA.
