Product review (5 stars): INSTALLED EASY - WORKS GREAT
I have an old Kenmore fridge, and through a little research found that this ice maker is a direct replacement for my old unit.  It fit without alteration what-so-ever.  The only thing that I needed from the old unit was the actuator arm that detects the ice in the ice storage bin.  Nut drivers help with the install.  I found that you pretty much need to plug the unit in (electrical connnection)  before you mount the unit.  Otherwise, it would be pretty much impossible to plug in with the unit installed, at least in my fridge.
