Wiper motor wiring problem

Tried to replace the wiper motor. Got a wmv-471k-rm. Mechanic installed it fine. The colors of the wires do not match up. New wiper motor has yellow, red, black, blue, orange, green, and white. 3 piece connector has yellow, blue, and red/yellow. 4 piece connector has red/black, green, red, and black wires. Which one goes with which? The instruction say to match them. They don't match. Bdj
