Installation - General Description and Overview 

The  XLifter  device  consists  of  2  main  components  -  the  control  module  and  the  EAS 
installation unit (EAS stands for Electronic Air Suspension). The control module (display unit 
with buttons) is used to control all settings and to inform the user of the operating status. 
The  EAS  unit  serves  to  adjust  the  wheel  height  sensor  signals  and  vehicle  tilt 
measurements. Communication of the control module and the EAS unit is wireless. 

The control module can be placed anywhere in the interior of the vehicle that allows for 
easy accessibility – as per user preference. The control module needs to be connected to an 
12V power supply (cigarette lighter socket).  Advanced users may cut the power connector 
and connect the cable to appropriate 12V junction point.  Installation with all cables hidden 
will  look  more  aesthetically  pleasing  and  the  lighter  socket  will  not  be  blocked  by  the 
plugged-in unit. 

The XLifter EAS unit is installed near the original air suspension control unit and connects 
with it via the supplied cable harness. The XLifter EAS unit is mechanically attached to the 
body of the vehicle after installation, thus serves also as an accurate tilt sensor.
