STEP 1—MOUNT THE COMPRESSOR
Disconnect the negative battery cable. Select a convenient
location to mount the compressor. This location should pro-
vide ample airow and be protected from airborne debris. The
mounting surface should be rigid to support the compressor.

will reach from the compressor to the anticipated location of
the ECU. Install a male tting into the threaded output on the
compressor head, see Figure “A”. Tighten the tting suf-
ciently to engage at least two threads with the pre-applied
threadsealant.DONOTOVERTIGHTENTHEFITTING.Mark
the four compressor mounting holes using the compressor
as a template and a center punch, then drill four 3/16" holes.
Mount the compressor using the supplied 10-32 x 1" machine
screw,10-32Nylocknutsand3/16"washers.SeeFigure“B”.

STEP 2— MOUNT THE MANIFOLD BLOCK
Select the valve block from your kit. Install the pressure sen-
sors into the back of the valve block. See Figure “A”. Select
a convenient location to mount the valve block near the com-
pressor. Mark the two mounting holes using the valve block
as a template and a center punch, then drill two 9/32" holes.
Mount the valve block using the supplied 1/4-20 x 2-1/2" bolts
and 1/4-20 washers and nuts.
STEP 3— MOUNT THE ECU
Select a location away from direct road spray and close to the compressor and valve block. Mark the two mounting
holes using the ECU as a template with a center punch. Drill two 3/16" holes and mount ECU using two 10-32 x 3/4"
machine screws and 10-32 Nylock nuts.
STEP 4— WIRE THE ECU, COMPRESSOR, AND VALVE BLOCK
Attach the tan wire and one of the ring terminals on the white wire to the studs of the pressure sender at PS1.Attach
the violet wire and the other white wire ring terminal to the studs of the pressure sender at PS2. Plug the six-pin
connector from the ECU into the six-pin connector for the valve block. Ground the compressor (black wire with ring
terminal) to a suitable location on the chassis.Attach the red/white wire with the spade terminal to the red wire of the
compressor. Route the red, yellow, and black wires to the battery. Ground the ECU to the negative battery terminal.
Attach the yellow wire to an ignition-activated +12VDC source. See Figure “A”.
STEP 5— MOUNT THE WIRELESS CONTROLLER
The wireless controller can be mounted in the cabin using the four Velcro pads. Place the pads on the back of the
controller and then rmly place the controller onto the mounting location. The controller should not be left outside
of the vehicle if not in operation.
STEP 6— ROUTE THE AIR LINE
Cut a section of air line tubing that will reach from the compressor to the valve block. Cut the air line tubing as
squarely as possible, insert the tubing into the male tting on the compressor, and then into the tting on the end of
the valve block labeled IN.
Cut a section of air line tubing that will reach from the valve block to one of the air springs. Cut the air line tubing
as squarely as possible, insert the tubing into the tting on the valve block labeled LF/LR, and then insert the other
end into the left front/left rear air spring. Use the Nylon ties provided to secure the air line tubing to the vehicle. Route
the tubing to avoid direct heat from the exhaust system and away from any sharp edges. Repeat this last step on
the other right front/right rear air spring and connect to the valve block port labeled RF/RR. There is a tting on the
valve block to accept additional tubing to route an exhaust line, labeled EXH. This is an option and not necessary
for proper operation.
STEP 7— USING THE WIRELESS CONTROLLER
With the Air Command kit and the air springs installed, you are ready to test the system. Re-attach the negative
battery cable, route the red wire with the fuse to a +12VDC power source, and place the 9V battery into the control-
ler. Turn on the vehicle’s ignition. Press the Mode button on the controller. The controller will display how much air
pressure is in the system.
