How do I install an ice maker when the plugs are different?

I have an Armana abb1924dew refrigerator. I am trying to install an ice maker, but plugs don't match, so I am trying to splice them. The colors are different though. The icemakers colors are blue, yellow, black, and green. the refrigerators colors are white, tan, violet, and green. does anyone have any ideas of how I should match them up?
