ACCUAIR: Rocker Switch
Congratulations!
Thank you for purchasing the revolutionary e-Level™ system by AccuAir.
This system manages the height of up to 4 Air Springs and offers never
before seen accuracy in all applications by constantly learning your vehicle’s
characteristics. Through the use of advanced height monitoring techniques,
this system automatically corrects for changes in load, whether driving or
parked, minimizing user input and maximizing accuracy throughout your
driving experience. To enhance the entire system’s performance and reli-
ability, the AccuAir e-Level™ also manages your Air Compressor(s) to keep
onboard air at an ideal pressure for your application.
To maximize functionality, the AccuAir e-Level™ allows you to select from
three distinct vehicle heights through a Rocker Switch:
1.) Ride Height (The height that you will typically drive your vehicle at).
2.) Low/Cruise (Typically set at 10% of your total suspension travel).
3.) High/Extra Clearance (Typically set at 90% of your total suspension
travel to increase mobility and clear driving obstacles).

VU4 (Valve Unit) Mounting:
Valve Mounting Considerations
• These valves are 100% weather-proof and can be mounted under vehicle.
• You will need to mount the ECU near the valves, so make sure that there is
enough space for both items.
Step-by-Step
1.) Find a at location to mount the VU4. This should allow enough room for
the airlines to be inserted without too much bending.
2.) Transfer hole pattern from the VU4 Mounting Template on page 22.
3.) Drill holes with a 3/16” drill bit and bolt the VU4 down with the included #10-24
Allen head cap screws.
4.) Place the ground eyelet from the VU4 wiring harness under one of the cap-
screws and make sure that this screw has good contact to chassis ground.
(Remove paint or coatings to expose bare metal)
5.) You may use this same location to place the ECU ground, so do not tighten
yet.

ECU Mounting:
ECU Mounting Considerations
• The ECU is 100% weather-proof and can be mounted under vehicle next to
the valves.
• The ECU can be mounted upright or on its back as seen below. (If back
mounted, back tabs must be removed)
• The following diagrams illustrate both “Standard” and “Optional” mounting
congurations.
Bottom Mounting (Standard):
See ECU Mounting Template
on page 24.
Back Mounting (Optional):
See ECU Mounting Template
on page 26.
Step-by-Step
1.) Find a at location near the VU4 (Valve Unit) to mount the ECU.
2.) Plug-In the Valve Harness while nding the mounting position to make sure
that it reaches.
3.) Transfer hole pattern from the ECU Mounting Template on pages 24 & 26.
4.) Drill holes with a 3/16” drill bit and bolt the ECU down with the included
#10-32 Allen head cap screws.
For optional mounting,
remove back tabs with
diagonal cutters and a le.

Pressure Sensor Mounting:
Tank Pressure Sensor Mounting Considerations
• Mount the Pressure Sensor vertically with the threads aiming downward to avoid
moisture build up in the sensor.
• Mount the Sensor close to the ECU to connect the pre-terminated sensor
harness that is part of the Main ECU Harness.
Step-By-Step
1.) Coat the threads of the Sensor and any threaded tting or adapter used in the
air supply system with a thread sealer to help prevent air leaks. We recommend
a liquid thread sealer for best results but Teon tape will work also. We strongly
recommend an Anaerobic Thread Sealer such as Loctite’s (P/N: 565)
2.) After tightening the sensor wipe off the excess thread sealer.

Sensor or Switch.

Installing & Wiring Air Compressor(s):
Air Compressor(s) Mounting Considerations
• There should be a fuse in between the Compressor(s) and the battery.
• The Compressor(s) get very HOT during operation. Make sure to leave space
between items that are susceptible to heat. (Wires, Nylon-Air Line, etc.)
Step-By-Step
1.) Find a location for the Compressor(s) to be mounted with good air
circulation.
2.) Transfer the hole pattern of the Compressor using the Air Compressor as
your template.
3.) Drill holes and bolt the Air Compressor(s) down.
4.) Install the Power Wire to the vehicle battery (12v+) with an inline fuse
(30Amps per Compressor) that is included with your Compressor(s) near the
vehicle battery (12v+).
5.) Install the Compressor Relay inline with the Compressor’s power line.
6.) Install the Ground Wire to vehicle/chassis ground. (Make sure to remove any
rust or paint to ensure a thorough ground)

Wiring Harness Installation Considerations
• The plugs that connect to the ECU will only t in the desired orientation. Do
not force the connectors into the wrong mating connector.
• Make sure to press all connectors on rmly until an audible “click” sound can
be heard from the lock.
• Route all wiring away from exhaust or other hi-temp areas.
• Use Rubber Grommets for areas where sharp metal could eventually wear
through the wire insulation.
Step-By-Step
•ECU Main Harness
1.) First connect the Main Harness at the ECU then route each section to each
component on the vehicle.
2.) Route the Rocker Switch sub harness (gray 7-wire bundle) to the inside of the
vehicle and leave until later in installation.
3.) Route the 3-wire Tank Pressure Sensor sub harness (green, red, and black
wires) labeled “P_SENS” to the sensor.
5.) Route the single yellow wire labeled “COMP_1” with a 3 Amp fuse to trigger
the Compressor Relay(s).
6.) Route the single red wire labeled “BATT_12V” with a 10 Amp fuse to the
vehicle battery.
7.) Mount the single black wire labeled “EC_GND” with the VU4 ground.
