    Follow the wiring diagram on the motor or see attached. Sub the yellow wire for the white in diagram. YOU also need to buy a NEW capacitor for the NEW motor of the value stated on the new motor. NOTE do not use the old capacitor over even if it is the correct size etc since it could be weak or defective and it could have caused the older motor to go bad.
