How to use a SLA7033M to control 5 wired unipolar 12v stepper motor?

(I am not sure that this diagram is correct because the model number is slightly different but I couldn't find one for my model number: smiley-confuse: )

I tried to understand the datasheet but it's very hard to understand.

This is the circuit I am following but I want to use SLA7033M instead of ULN2004A

Can someone provide me with a circuit diagram or fritzing diagram to follow?

I also have a question when I connected the center wire of stepper to + and other wires - the motor worked and even when I switched the poles it worked fine. Is there any disadvantage of reversing the polarity?
