Wiring Help Needed

[qtband]

I bought a Tao GK110 and someone put a new motor on it. I also got the blown engine in the deal. Everything is hooked up except the wiring. I have all of it sorted out except the wires from the motor. In the picture, "A" is what comes out of the engine on the kart now. The plug doesn't match the kart. "B" is the blown engine with the plug that matches the kart. How can I tell what wires to splice together?
Thanks, Ken
