Could any one give me a bit more info on wiring these motors up?

If you check the link it gives all the specs. I’m basically wondering if I should run it bipoler series or bipolar parallel with 12v. My controller is the sanguinololu with step sticks.
There’s a wiring table in the PDF at that page.
Here’s a qualitative reference: http://www.astrosyn.com/shopimages/technicalguides/Guide%20to%20Stepper%20Motor%20Drive%20Selection.pdf
- higher torque at low speed for series
- flatter torque-speed profile for parallel.
Pick your poison. 
sounds like i can use series for my extruder drive and probably parallel for my x,y,z.
The “parallel” option in the 6-wire mach motion doesn’t look to be particularly relevent/useful unless series gives you difficulty. It’s not a fully parallel configuration as could be achieved with an 8-wire stepper: http://www.linengineering.com/line/contents/stepmotors/pdf/Product_Guides/Lin_RG_StepMotorBasics.pdf
That pdf has some good info in it. I may try to get one hooked up tonight in series and see how it does.
The drivers I have are 4988’s
