New CTC user - Advice Needed

I've been taking a few printers apart to see if I can get spare parts. None of them have the same stepper motors though in square casing.

Yes, I found that Not all stepper-motors are wired the same internally, also,
even tho they look the same and connectors look the same,
They may not work until you reverse the 2 center wires at connector.
(wires can be reversed at either motor or at Mobo, to fix the problem)

(I reversed wires Inside of one motor, to fix it, but that is not easy)
