If you buy the blower motor with the wheel already installed on it all you have to to is unscrew all of the screws around the motor, pull the purple primary wire off and the ground will come off with the bolts around the motor and just pull the old one out. take the vent hose off the old one and put it on the new one, attatch the primary wire and put the motor back in with all the screws making sure the ground is tight against the metal on the new motor.
