Here is some more info regarding the micro limit switch replacement. Refer to the pics below of my old defective switch lying next to one of the two switches I bought from the Amazonians.
The new switch has three wires, the old switch had two. Connect black to black (just about always, right?), Then connect the gray wire from the old switch to the blue wire of the new switch. You can snip off the red wire or coil it up.
Put your spoiler wing in the down position by whatever means and place the new switch in position on the bracket so that the roller on the end of the lever touches the raised cam on the right side of the drive gear. Slide the switch toward the cam until the button is depressed on the switch. Hint: it takes very little pressure to activate the switch. Now mark the position of the switch on the bracket.
Put a drop of your favorite high performance adhesive on the back of the switch and glue it in place.

When in position, wires on original exit to the right, wires on replacement exit down.
