Wiring an 8 wire stepper motor to a v2 shield

I'm have my project set, I simply want to upgrade my 4 wire bipolar stepper motor to an 8 wire unipolar stepper motor, but I can't seem to get it wired up. I've tried a couple configurations but I want to see if theres a proper way so that I don't damage the motor or shield.

Can you say what motor and perhaps link to the datasheet? I know of 5 wire and 6 wire motors, but have not heard of an 8 wire motor.

Why would an 8-wire motor be an upgrade from a 4-wire motor?

The important figure is the torque.

Also, if the V2 shield (whatever that is) is a simple h-bridge then you will probably get better performance with a specialized stepper driver and a higher voltage power supply.

Well in this case the 8 wire motor has more torque

But you have not posted a link to its datasheet as requested in Reply #1
