Has anyone ever drawn up the schematic of the vacuum lines and actuators for the County air con system?

I'm about to 'cos I've got the dash out to repair the heater/air con control panel - but there's no point re-inventing the wheel if someone has already drawn it up.

Also, is there a vacuum actuator in the fresh air duct under the LH wing/mudguard? There appears to be a vacuum line heading under there.

BTW, I have drawn up the wiring diagram for the rear wipers and washer - something not shown in the County workshop manual - it is very similar to the Defender wiring.
