They should have added another couple of bits to the scan. I suppose that would have doubled all of the file sizes -- as usual, the decision was made by some faceless beancounter.

Wading through all of the menus to get where you want is a pain, too. The W124 version at least allows you to skip the opening "video" but the W123 makes you watch it every time, a waste.

Speaking of the 123 climate control system, does anyone have a schematic of the connections to the Klima relay (part 001 545 74 05) that controls the a/c compressor on the 1985 300D? It appears to be unique to this model year and I can't find it on any of the wiring diagrams.

I also have a paper copy of the "Service Manual/Heating, Air Conditioning/Automatic Climate Control/Model 123" (copyright dated 1988), and it doesn't mention that relay.

A PO replaced the Klima relay with a jury-rig and I'd like to put the system back to stock but don't know how to wire the socket.
