Nema 17 motor wires

Hi,
I bought a sc42sth47-1648a 1.8 degree 2 phase motor to use with a different extruder setup. When I received the motor, there are 4 wires sticking out of the motor with no connector at the end. I received no wiring diagram for the motor. The wire colors are black, blue, green and red. I looked into the opening they come out of and the red and green come from the right and the blue and black come from the left to exit that opening.. Anyone around that could give me an educated guess or knows the order I should put them into a connector to plug onto a ramps 1.4 board?

Thanks, Vance.

Thanks for the wiki link. Just did not want to damage the motor by putting wires in a random order.
