Product review (5 stars): I discovered it lacked electrical continuity in one of the wires (open circuit) going to that connector so I used the old harnes
This was an exact ice cube maker replacement--it is identical to the old one.  Installed it myself and we are now overflowing with ice cubes and NO water leaks. Just read carefully and follow the instructions provided and use a 12-inch level to insure the unit is sitting just right. I had a problem with the new wiring harness.  I discovered it lacked electrical continuity in one of the wires (open circuit) going to that connector so I used the old harness and it worked fine.  Don't discard any of the parts you don't immediately use or from the old unit until the new one is producing new ice cubes.  Don't get cute and mess with any of the factory settings.  The instructions emphasize this. I followed my own advice.  This unit listed date of manufacture as 2010.  If you are debating investing in this unit, my advice is do it before all the new ones are all sold out.  It is worth the $60 odd bucks for the convenience.  There is probably a U-Tube video out there to show you how to install it.  It is not difficult, just remember to turn off the water to the ice make first.
