Engel Pump Wiring

These two pictures show the wiring of a usual Engel Pump without Auto Trim. Although the pump is equipped with a third microswitch I have only wired it as a usual pump which has only two microswitches. I do not use the Auto Trim yet, but I will do soon. The wire colors of my pump do not match with the colors of the wiring diagram so I wrote the colors of the diagram in words. If the pump does not work as it should do with that wiring the two wires which go the motor positive and negative have to be changed. Then it will work correctly.
