This one seems to need a different wiring setup than the others I have.

Richard, is there a missing terminal point at the top right corner where it is broken off?

I would expect that the remains of the wiring on the unit would give a hint at the wiring scheme. 

Top left is output Line
Bottom Left is Neutral
Bottom Right is Input Line

Measure resistance between the two bottom posts.  Turn the Variac knob.  The resistance should not change.

Measure resistance between the top left post and one of the lower ones.  Turn the knob. The resistance should change.

That would tell you it's correct as described above!
