Syncrowave 250 remote foot controller wiring confusion

[big mike]

I'm not sure about the wiring but do you have the correct pot?
Miller uses a 1K and Hobart appears to use a 25K

Hi, maybe someone can clarify which wire from the rheostat in the foot controller goes to C,D, E on the plug.
The manual states “D” is the common, but the PDF on the foot controllers seems to show E as the common.
In both cases the manuals don’t explain which side of the rheostat C is on. One side has 0 ohms at rest and the other side has max ohms. Does it matter?
I’m adapting my Hobart remote and thought I’d ask before I experiment to figure it out. I suppose the worse that will happen is the machine will be on full power from the start if I get it backwards. But the part about which pin is the common is a bit confusing.
Thanks,
Herb
