The headlight leveling control unit is located under the driver's side of the dashboard. The headlight leveling control unit uses the voltage signals sent from the front and the rear suspension stroke sensors to determine the voltage signal (about 2-11 V) send to the left and right leveling motors to adjust the headlight's vertical position.
