Arduino + Stepper

Hi! I have an Arduino nano and a Minebea PM55L stepper motor and I have to connect these two together. I read the Arduino tutorials, and got a ULN2003 chip. The thing I am unsure of is the power supply and which wires of the motor do what or should be connected to what. There's 6 of them and I really don't want to fry anything if at all possible. Could somebody help out, please?

The 6 wires are 4 phases and 2 ground. The grounds can be connected together.
