Constant Speed Solenoid - what component number on the wiring diagram Legend?

[jedwards]

Gentlemen,
The CSS on my 1967 250SL is still giving me grief, so I am attempting to understand it's electrical "logic" and how it gets power and under what circumstances. However I am having trouble locating the CSS or the throttle switch on the  circuit diagrams in the Tech Manual section http://www.sl113.org/wiki/Electrical/WiringDiagram

Can anyone tell me what number components these are on the legend?

Hi,
the CSS was only used in cars with auomatic transmission (before 1970) and with A/C (after 1970). Because both were extra options I assume it was not part of the standard wiring diagram.
But there was an extra wiring diagram, e.g. for 230SL, see attachment.
For possible wiring colours see here: http://www.sl113.org/forums/index.php?topic=21918.0
