The voltage varies dependant on how close an object is to the sensing ring on the torch Also I'd there any chance anybody would recognise these drives having a hard time finding the enable for them

First thing I would do is eliminate as many possible wires as you can. Then try and trace back the ones you have left to see if you can discover what they do. Also the enable might be "on" and readable with a meter when jogging slow where the velocity input voltage would vary with speed.

Does the capacitive sensor go to the board in the schematic? (unfortunately that schematic is pretty fuzzy especially signal names)
