The color wiring on the motors that came with the Prusa i3 are, red, blue, green and black in that order from left to right.
I have other motors with blue, yellow, green and red from left to right.

Can these be used? They have the correct ends.

There is no standards colors for stepper motors. its what ever the manufacture had laying about on the day

There are 4 pins on the reprap end, just check the first two are connected and the last two are connected and there is no connection from 1,2 to 3,4 with a multi meter.

If they are wrong those connectors are really easy to pop the wires out and swap them around should it be needed.

Thank you for replying.
I'll see about changing the ends or just use the other motors.
Any changes needed to the firmware? or ???.

Different motors will probably need a different vref (variable resistor on stepper motor driver for most cheap electrics)

If your firmware is setup to expect 1.8degree steppers and these are 0.9degree steppers then you will need to double the steps/mm in firmware.
