Dear Ken,

> manget confirm that the helium sensor connects to the Black Plug?
Yes, it's the black plug. Attention: the pinout is different compared to
Oxford/Bruker magnets: While the latter use pins A/B/D/E, Varian/Agilent
magnets use pins A-D for probe 1 and E-J for probe 2 (with connections
V+, I+, V-, I- each).
> Second, I'm curious about experiences converting Varian/Agilent magnets

No problem - Bruker did this many times. All you need are adapter plates for
the top and bottom flanges (which are a bit different in terms of hole diameters
compared to Oxford or Bruker magnets).
> Were you able to make things like N2 and He sensors work with their software/consoles?

Varian/Agilent magnets all have their standalone helium and nitrogen sensors -
no need to fly blind. But reading them out from the software is more difficult
(specifically the nitrogen meter), whereas I guess that plugging in the Bruker
console readout plug will not work without modifying the cable.
Cheers
