I have added John's schematic to my Wiring Diagram page at -

There is also a diagram of the Western Union 9797 Wiring Cabinet for the 28ASR

I don't know if many have the Western Union cabinets with their version of a LESU, but I chose this out of the large file of WU drawing as the,to me, most understandable of those for 9100 wiring cabinets.  Got it stitched from two pages into one that is easier to read on the screen.  If one wanted to print, then you might have better results printing pages 30 & 31 of the big PDF and manually stitching, YMMV.
