Labelled the parts so you get more of a feel.. I will test this on a system as soon as I get it ... I'm more than confident it will work.. Just to stop any 0v confusion... I only have access at points A , B and OUTPUT so there is no 0v.. This is to replace an existing angle sensor that is now defunct!
