OK....that makes things somewhat clearer, as to how I will hook them up.

I must be doing something wrong on my end for checking. I get the same
ohms no matter what. Should I be holding some wires together and then
check..???. Bill, do you know what the red and green wires and their
tracers were for(eg. step and direction..etc)now that I know the black
and white are center taps.

Thanks again
