Using the pin numbering from Walter for the AMP 746789-1 female 50 pin
connector and defining the pinout from the point of view of the female
connector that plugs onto the exterior side of the cryostat feedthrough
the pinout is:

          The extra grounds, shield ground pins,
          are pin numbers: #1 and #50.



The pin numbering of the  AMP 746789-1  female 50 pin connector
looking at the surface where the pins plug into it is:

Note that the pin number labels on the NORCOMP 50 pin D-Sub
connectors are different but we will use the AMP standard shown
above.
