Ice maker would not work

Disconnected the power and then the water line. Removed the cardboard shield on back of the refrig. Then removed the faulty solenoid which was held in place by one bolt. Removed the two plastic water hoses and two sets of electrical connectors. I then reversed the process to install the new solenoid. I encountered two challenges. The new solenoid had a plastic housing that had to be removed and one set of the electrical connectors required an extension. The extensions were included with the solenoid, but there were no instructions.
