 Thank you to all the people who got back to me with help. I'm pretty sure
now that pin 23 is a shield connection for the sensor wire. I have never
actually seen one of these in the flesh, so I don't know what it looks like.

If anyone would like to host my new version, or just wants a copy, let me
know. I have reformatted it slightly from the original on to an A1 sheet
and it should be fully scalable. The PDF has the original scan underneath
on a separate layer.
