Hi, Sandy - I'm finally getting around to connecting the pen lift servo to my Polarshield (early version). I have a Polarshield without the case, and I'm not sure which set of three pins it's supposed to plug into - there are four sets of pins directly below the touchscreen.I I've actually tried plugging into all of them without success so far. (By no success I mean that if I plug it in and press "pen up", "pen down" on the touch screen nothing happens). Should the ground/neg. wire (ie brown or black wire) be on the left or right?

Hurray, glad you got it sorted. Yes there's lots of answers out there, but like you say, very poorly organised. Googling sometimes works surprisingly well, but of course, I know exactly what to google for cos I wrote most of it 🙂
