The direction of rotation can be changed by changing polarities.
  • Switch on ignition, connect respective control motor to vehicle wiring harness and select a setting on operating and display unit to set control motor to desired position (e.g. mid-position). Wait until control motor has moved to desired position and switch off ignition.
  • Route wiring harness so that it cannot come into contact with any moving parts (e.g. actuating arm on control motor).
