13. After choosing a mounting location for the Air Ride Technologies control unit, you have several choices of how to wire the unit to control the inflation and deflation of the bags. The owner of this truck wanted ultimate flexibility, so the truck was wired so he could control each bag individually. This is accomplished by simply pushing the buttons upward to inflate, and downward to deflate. The pressure reading shown in this photo is the pressure of both rear bags, and a button allows the driver to toggle between front and rear pressures at will.
