struggling to figure out color connections (4 replies)

Hey everyone, building a Mendel using Ramps 1.4, my steppers are Kysan 1124090 motors.

They have the following colors and letters from the spec sheet:

A=Red
B=Yellow
C=Green
D=Blue

My Ramps board is asking for 2B, 2A, 1A, 1B

I am really confused on how I should connect my wires to my Ramps board, I have been reading many different things for different steppers.

Any help would be greatly appreciated! Thanks!
