I'm trying to replace one of the three-way light switches in my garage with a motion sensor. But I'm confused by the wires on the existing switch. I thought the hot wire goes to the black screw labeled "common" but instead the existing switch looks like this:

  • black screw/common = red wire
  • brass colored screw on same side = black wire
  • brass colored screw on other side = red wire
  • 4th screw = bare copper wire (I assume this is the ground)

My new switch has

  • black = hot
  • white = neutral
  • red = primary load
  • green = ground
  • blue = ?

Which wires should I connect on the new switch?
