Well if you dont get the function you want from the up down button,,,,ie when you push up the thing goes down....and when you push down it goes up,,,,then just swap the 2-4 leads either at the switch or at the motor,,,it will give the same effect,,,,,and in a few day I might find my manual and give you color codes to the wires if I can find them,,,,,,,one rule of thumb,,,any wire that is black with a white stipe is a ground wire,,,negative lead...Jason
