T2X uses same wiring as HAM II/III/IV/V.  The difference is a
larger casting (with through bolts) and a third bearing race.

The only difference in the controllers between T2X and HAM IV/V
is the additional LEDs for CW/CCW (and possibly paint color
depending on the era).  Compare parts lists in the manuals at
various stages of production and you will find part numbers
leapfrogging one another as improvements were introduced in
first one then the other series of rotors.

... and yes, the original T2X included the terminal strips ...
I have two of them with terminal strips from the late 70's.
