Secure the ring terminal to a grounded component of the chassis.
Next, route a length of wire from the pressure switch to a positive 12 volt, 20
amp, ignition activated power source on the vehicle. Cut a length of 16 gauge
wire from the 6' length included with this kit. Crimp a blue female terminal
connector onto the black lead from the comprssor. Install the female terminal
connector over the remaining spade on the pressure switch. Connect the lead
from the pressure switch to the 12 volt wire with a wire connector. Slide the wire
connector over the existing wire and insert the un-stripped lead from the
pressure switch into the wire connector. Close the wire connector over both
wires with pliers see Figure "G".

PANEL
FOR
ILLUMINATION
From the 15' length of 18 gauge wire, cut a length that will reach from the
gauge panel to a dashboard illumination wire. This will allow the gauge panel light
to be activated with the dashboard lights. Strip one end of the wire 1/4" and crimp
a red female terminal connector onto the wire. Slip the female connector onto
either spade on the back of the gauge see Figure "I". Attach the other end of the
wire to a dashboard illumination wire using a wire connector. Slip the wire
connector over the existing dashboard wire and insert the un-stripped gauge
panel wire into the wire connector. Close the wire connector over the wires with
pliers see Figure "G". Route a length of 18 gauge wire from the gauge panel to
a suitable ground source. Strip both ends of the ground wire and crimp a red
female terminal connector on one end and a red ring terminal on the other end.
Slip the female terminal connector over the remaining spade on the back of the
gauge and secure the ring terminal to the ground source see Figure "I".

THE
SYSTEM
With the Air Control Accessory Kit and air helper springs installed,
you are ready to test the system. Re-attach the positive battery cable. Turn
on the ignition. The compressor will start and build pressure in the system.
Push the paddle switch upward to inflate the air springs. The gauge will
display how much air pressure is in the air springs. Inflate the air helper
on the ignition. The compressor will start and build pressure in the system.
Push the paddle switch upward to inflate the air springs. The gauge will
display how much air pressure is in the air springs. Inflate the air helper
springs to 70 P.S.I. and check the fittings for air leaks with an applied solution of soap and water. If a leak is detected at a tubing
connection, check to make sure that the tube is cut as square as possible and that it is pushed completely into the fitting. The
tubing can easily be removed from the fitting by first releasing the pressure from the air spring, then by pushing the collar towards
the body of the fitting and then pulling out the air line tubing.

OPERATION
The air control accessory kit allows the air springs to be inflated from the inside of the vehicle. Push the paddle switch up
to inflate the air springs and down to deflate the air springs.
If the air compressor fails to operate for any reason, air can be introduced into the system by using the manual inflation valve
installed with the air accessory kit. This can be accomplished by inflating the system through the manual inflation valve.
