Installing the AutoPilot V2 Kit
INSTALL COMPONENTS
For a complete schematic, please see g. 15. (pages 10-11)
BEST PRACTICE IS TO LOCATE THE MANIFOLD UNIT INSIDE THE VEHICLE. IF
EXTERNAL MOUNTING IS DESIRED, THE MANIFOLD MUST BE LOCATED IN AN
AREA SHIELDED FROM DIRECT WATER SPRAY FROM TIRES OR CAR WASHES. THE
MANIFOLD SHOULD BE CONSIDERED “WATER RESISTANT” NOT “WATERPROOF”.
Layout
1. Plan component location rst. Ideally, the manifold should be located above the
compressor and tank if possible to avoid compressor ingested water from gathering in
the manifold. This is most important for vehicles operated in below freezing climates.
2. Prior to mounting components, check to make sure:
• the electrical harness connections will reach the manifold and compressor.
• the compressor leader hose will reach the tank.
• the air lines will route cleanly through the vehicle without kinking or bending.
Be sure to install all components as far as possible from any heat sources. Plan and prepare
harness and air line routing thru the vehicle. Eliminate all sharp edges that could chafe. Use
grommets when passing through compartment walls.
Prepare and install the compressor
1. Prepare the compressor intake. If the compressor body is mounted inside the vehicle,
attach lter to port on end of compressor (g. 15). If compressor is located outside the
vehicle, snorkel inlet lter to dry location inside vehicle using components supplied with
compressor.
2. Center punch and drill four holes using the template on page 19.
3. Attach using the hardware supplied with the compressor.
If the harness must be lengthened, use properly sized butt connectors and wire. If extending
the power/ground wires, use 8AWG wire minimum or contact Air Lift for more information.
The supplied harness is only capable of powering a single compressor. If installing dual
compressors, a second dedicated power wire is required. Consult the Electrical Schematic
section for proper wiring, and contact Air Lift for an optional second compressor harness
(part number: 27679).
Manifold
1. Position the manifold in a desired location. Make sure the manifold mounting surface
is at.
Mount the manifold to the body either horizontally (g. 1a) or vertically with the ports facing
toward the ground (g. 1b). Do not mount the manifold upside down (g. 1c). Proper manifold
mounting will help prevent water from settling in areas sensitive to freezing.
2. Fasten the manifold using the two self-tapping screws. If the mounting surface is not
at, add washers to space the manifold up over surface irregularities.
3. If needed, a manifold mounting template can be found on page 17.

Air Lift PerformanceAir Lift Performance
Air compressors intake moisture (humidity) from the outside air source and will deposit
water in the air tank. The AutoPilot V2 system includes a lter that will greatly reduce the
potential for moisture to enter the manifold, however, tanks must be regularly purged to
eliminate the possibility of water entering the manifold. Be sure to provide easy access to
tank drain/ll valve (preferably outside the vehicle). This is an automatic draining lter and
does not need servicing. If you nd this lter to be plugged, it will need to be replaced. If
using an engine driven compressor, the life of the provided lter may be reduced due to the
increased potential for oil being introduced into the system.
Tank pre-assembly (see g. 15)
1. Per the diagram on pages 10 and 11, install the lter to the tank with supplied ttings/
adapters or remotely mount the lter using the supplied ttings, P-clamp and self tapping
screw. Be sure to mount the lter in the correct orientation.
This is a one-way lter. The arrow at the top should be pointing in the direction of the air
ow from the tank to the manifold (g. 15b).
This is an automatic draining lter that does not require servicing. If you nd this lter to be
plugged, it will need to be replaced. The tank will need to be purged periodically to reduce/
eliminate the potential of moisture entering the manifold.
Tank install (see g. 15)
1. Using the tank feet as a template, drill holes for hardware assembly.
2. Attach the tank using the supplied hardware.
3. Cut an appropriate length of hose from the manifold port T, to the PTC tting on the lter.
4. Route the drain/ll air line with a schrader valve (preferably outside the vehicle).
5. Install the supplied drain tube (soft hose) to the bottom of the lter and route to a location
outside of the vehicle.
When cutting plastic air line, only use a standard hose cutter like (Air Lift part number 10530)
or razorblade. Cut all hose ends square and as smoothly as possible. See hose cutting tips
on page 6.
INSTALL HARNESS
1. Disconnect the battery ground while installing the system.
2. Compressor / manifold connections (see g. 15)
• Attach the manifold connector, it will “click” into place once fully seated.
• Mount the compressor relay in a preferred location using a self-tapping screw.
• Cut off the spade and eyelet from the compressor power and ground wires.
•Strip 1/4” of wire casing from the compressor wires.
•Strip 1/4” of wire casing from the black and pink harness wires.
• NOTE: Use an appropriate terminal crimp tool to ensure a good connection.
This represents the top of the vehicle frame or any custom setup (and is the same for gures 1b and 1c).

•Using a butt connector attach the RED compressor wire to the PINK harness wire.
•Using a butt connector attach the BLACK compressor wire to the BLACK harness wire.
• Carefully apply heat (preferably with a heat gun) to seal these connections.
3. Battery / ignition connections (see g. 15)
• Identify the power, ground, + ignition leg of the harness.
• Ground: 10AWG black wire; Power: 10AWG red wire; Ignition: 18AWG pink wire.
•Route power and ground leg of the harness free from any heat source to the battery.
• Using a butt connector attach the red wire to a fuse holder.
•Attach an 3/8” eyelet to the other end of the fuse holder and attach to the positive
battery (+) terminal.
•Attach an 3/8” eyelet to the black wire and attach to the battery ground.
•Route the 18AWG pink wire to a key switched IGNITION source that remains on
during cranking. Examples include: ECU, fuel pump.
Do not select an accessory source. If the AutoPilot V2 display shuts off while starting the
vehicle, this is not a true ignition source.
• Using a butt connector attach the pink ignition wire to a fuse holder.
• Select ignition source and attach the fused ignition wire.
• Use fuse adaptors as necessary.
4. Display
• Route the display cable as desired to the preferred operating location.
•Attach the display cable to the main harness cable (small white 3 cavity connector).
5. Reconnect the battery.
INSTALL AIR LINES
Use a standard hose cutter (Air Lift part number 10530) or razorblade. Cut all hose ends
square and as smoothly as possible.
1. Route and attach the air lines to the air springs.
• Route air lines free from abrasive edges and heat sources.
2. Attach manifold port FL to the front, drivers side left spring.
3. Attach manifold port FR to the front, passengers side right spring.
4. Attach manifold port RL to the rear, drivers side left spring.
5. Attach manifold port RR to the rear, passengers side right spring.
6. Attach manifold port T to the PTC tting previously installed on the lter.
7. Manifold port Eis the exhaust port.
• Port E can be left open, or routed to a preferred exhaust location.
Air lines should be pushed in rmly, with a slight back and forth rotational twist – check the
connection by pulling on each line to verify a robust connection.
Release the air line from the tting by releasing air, pushing on the line, depressing the ring
towards the tting, and then pulling the hose out of the tting.
NPT ASSEMBLY INSTRUCTIONS
1. Inspect the port and tting ensuring both are free of contaminants and excessive burrs
and nicks.
2. Apply a stripe of liquid pipe sealant around the male threads leaving the rst two threads
uncovered.
3. Screw nger tight into the port.
4. Wrench tighten the tting to the correct turns past nger tight position (see table 1
located on page 6).
NEVER BACK OFF AN INSTALLED PIPE FITTING TO ACHIEVE PROPER ALIGNMENT.
LOOSENING INSTALLED PIPE FITTINGS WILL CORRUPT THE SEAL AND CONTRIBUTE
TO LEAKAGE AND FAILURE.

•1/4” hose = 1” hose bend radius.
2. Hose to tting
•No side loading on tting from hose.
• Hose straight for 1” before bending.
3. Hose cutting
• Cut hose perpendicular to hose length.
• Inspect hose for scratches that run lengthwise on hose prior to insertion.
•Use proper hose cutter, cigar cutter, or razor on at surface.
4. DOT/SAEJ844 air brake hose data
• Maximum working pressure of 175 PSI.
•Not to be used for frame (body) to un-sprung mass connection, use a braided leader
hose for this moving connection.
AutoPilot V2 is an advanced pressure-based air suspension control system, that uses state-
of-the-art software algorithms to calibrate or map the control system to your vehicle. Once
the system is calibrated, the algorithm predicts required “valve open time” to move the air
suspension to achieve preset target pressures. AutoPilot V2 has 8 programmable presets,
allowing the user to input 8 different combinations of the 4 corner air spring pressures.
After installing AutoPilot V2 in your vehicle, please follow the steps below to properly setup
your new system. If changes are made after installing and calibrating the system such as
changes to air springs, lines, tank, compressor, or other vehicle modications, the system
must be recalibrated to maintain accuracy.

Program Presets
Program Preset 1
Preset 1 should always be entered as the desired
ride pressure for the RISE ON START function.
Determine desired ride pressures: press
buttons (1+5) simultaneously to toggle display
to MANUAL mode. Manually activate each
corner (see MANUAL mode section page
13) to achieve desired “normal driving” ride
pressure (g. 11). Program preset 1: press
buttons (1+5) simultaneously to toggle display
to PRESET mode (g. 12). Press and hold
button 1 for 3 seconds to set preset 1. Release
button and actual air spring pressures will
appear (g. 12). Fine-tune the pressures by
pressing up/down buttons. Press and hold to
scroll. Press buttons (1+5) simultaneously to
save and exit.
Program Presets 2-8
You are now free to program the additional 7
presets to desired pressures. Typical presets
can be:
•“Low”: set pressures to the lowest
possible pressures for extreme low
driving stance.
•“Front up”: for speed bump or driveway
clearance.
• “Rear up”: for added load of
passengers, equipment.
•“Play”: for those that want to enjoy their
air suspension freedom, AutoPilot V2
has a special function that recognizes
side-to-side presets. When left side
pressures are equal, and right side
pressures are equal but >25PSI
different than left, the algorithm will
activate side to side instead of front
to back. It will also equalize all air
spring pressures when exiting the
“play” preset, conserving air by using
the high pressure side to inate the
low pressure side. Pairing two “play”
presets together allows side-to-side
activation that consumes far less air
than manual mode activation would
consume.

Now that your system is set up, it’s time to use it. If changes are made after installing and
calibrating the system such as changes to air springs, lines, tank, or compressor, the system
must be recalibrated to maintain system accuracy.
There are two operational modes: PRESET and MANUAL. Pressing buttons (1+5)
simultaneously will toggle between modes. After 10 seconds of non-use, the display enters
standby where the LCD dims. Any button hit will “wake-up” the display and allow users to
activate the system. See mode operation below for more details.
PRESET Mode
1. If display is sleeping, press any button once to “wake up” the display. If display is
illuminated, go to the next step. Press of any button will display the programmed preset
pressures for that button. Users can quickly view each preset prior to activating to make
sure they are selecting the desired preset.
2. A 2nd button press of the same preset button within 2 seconds will activate it. The system
will iterate up to 6 times to achieve the preset target pressures by +/- 3 PSI. The display
shows PLEASE WAIT as it iterates, then will ash SUCCESSFUL when achieved or
UNSUCCESSFUL if not able to achieve the target pressure window.
3. Micro adjust to ±1 PSI: If more accuracy is desired, double press the same preset and
the system will rene pressures closer to target. This is often necessary when target
preset pressures are LOWER than current pressure. Accuracy can be improved by
rolling the vehicle straight while activating the preset.
If the system indicates UNSUCCESSFUL, refer to troubleshooting guide on page 13.
PRESET Mode: Improve Accuracy
If system reads SUCCESSFUL but pressures are consistently lower or higher than target,
you can improve rst attempt accuracy by going to Calibration Menu (g. 5) and pressing
button 2. Adjust the ADJ value to a higher number if rst attempt pressures are lower than
target. Adjust the value to a lower number if rst attempt pressures are higher than target.
WHEN A PRESET IS ACTIVATED THAT LOWERS THE VEHICLE SIGNIFICANTLY BELOW

MANUAL Mode
1. MANUAL mode allows the user to ll or exhaust each spring independently. The display
will show arrows above and below the pressures to indicate manual control mode (g. 17).
The arrow will be solid when the spring is lling/exhausting, and outlined when not active.
2. The system detects button press time. For a very short (<0.1sec) duration press, the
system will open the valves for a dened “burst”, changing pressure minimally so users
can ne-tune their pressures. For a longer than 0.1 sec duration press, the valves open
as long as you hold the button down. If a button is held active, the ll/exhaust will time
out after 10 seconds.

Troubleshooting Guide
Leak Testing and Detection
Leak detection
1. A leak can be dened as a loss of pressure of more than 5 psi over an 8 hour period. Be
aware that ambient temperature change has an effect on pressure that may seem like
a leak. For example: a change of 10deg Fahrenheit up or down from your baseline will
have an approximate gain or loss of indicated pressure of 2 psi. If a leak is suspected
after including any temperature change, then proceed to #2.
2. Spray soapy water (1/5 Dawn brand dish soap to 4/5 water) on suspect ttings and hose
connections and look for any bubbling caused by air leakage.
3. Fix leaking connection (review pg. 6 for help on NPT ttings and air line connections).
4. Wipe down sprayed connections with rag to remove any residual soapy water.
Dawn brand dish soap will not corrode the metals (aluminum, brass, steel) with which it
comes into contact.
PROBLEM CAUSE SOLUTION
Compressor doesn’t run There is a blown fuse or relay, bad ground, or poor
electrical connections.
Replace the fuse, check the ground wire, or check
the compressor connector
Compressor runs all the time. The compressor relay is defective or there is a leak. Replace the relay or locate the leak and repair.
Air spring or tank leak. Fitting seal or air line is compromised. Check to make sure air lines are seated in connectors.
Inspect ttings with soapy water. Trim hose or re-
seal tting.
Nothing happens when the vehicle is key-on
ignition active
There is a blown fuse or a poor connection. Replace the fuses and check the electrical
connections.
The display does not light up. There is a blown fuse or a poor connection. Replace the fuses and check the electrical
connections.
Compressors runs all the time but doesn’t ll the tank. Compressor in-line check valve fitting has been
overtorqued.
Loosen tting and check again. Replace if needed.
Display shows UNSUCCESSFUL. “Double Click” for Preset not completed within 2
second window.
If display is in sleep mode, click once to “Wake Up”,
then “Double Click” desired preset within 2 seconds
of each press.
Adjust ADJ value or recalibrate system to reduce
number of iterations.
Calibration may need to be adjusted or system may
need to be recalibrated.
Tank pressure settings changed.
Vehicle load changed signicantly. Attempt recalibration.
Air springs/air lines/tank changed.
Display shows PRESSURE SENSOR FAILURE. ECU has detected a pressure sensor operating
incorrectly.
Only manual mode can be used to operate
suspension. Contact customer service immediately
to resolve the problem.
