help!

Hi every one,
Sorry about the basic questions but i am very raw at this. I have
bought three of the Gecko 201 closeout drives and I wish to ask a few
dumbo questions, here goes!,
The stepper motors I have are 3 volt , 4 amp 6 wire jobs and I want
to get the most torque out of them with no real concern about fast
feed rates so , do I wire them as 4 wire leaving the center taps
vacant, if so what is the resistor value required? or do i 4 wire
using two end taps and the two center taps , again what size
resistor? I know the guide that came with the drives does explain it
but as I am so hopeless with this stuff that i would rather ask the
experts than stuff the drives!
kindest regards
Mark
