  1. To change the rotation direction of  the motor one of the two coils needs  to be reversed polarity. 
  2. Use a Hobby knife and gently lift the small plastic tab and pull out the cable from the connector from position 1 as in the photo. 

  1. Repeat this for the cable in  position 4 (position 2 is empty) so  both cables is loose. Now place the cable that was in position 1 to position 4 and the cable that was in position 4 to position 1. 
  2. This is how the cables is connected once they are moved, compare to the photo in the top.
