Product review (4 stars): Tricky to Install.
The cable adapter for older refrigerators, make this a tricky install because the cable is too long for a clean straight forward install.  They should have made the ice-maker with either cable, but they must sell more of the newer type so this simple job turned into a bit of a challenge. This review is to help save others with older units as mine, some time.  I ran the cable straight up between the first mounting bracket(left) and the ice-maker body.  I then screwed in the screw to the first mounting bracket(left)to hold ice-maker into place.  The cable comes over the top and down to the left and under the ice-maker and plugs into the power socket.  The original cable came out of the socket and moved right under the ice-maker and back behind the ice maker.  This can still be done, but as others have commented, the cables will be in the way of the catch basin and the ice-maker arm.  By doing it my way you'll have no issues there.  The only other issue is a small one.  There is a plate that hides the ice-maker plug, when its plugged into the power socket.  The plate can be manipulated by bending the small dog ear out a bit, to make room for the cable, which is going to the left side of ice-maker instead of to the right.  I actually plugged the cable into the power socket and then clicked it to the left a couple of times to change the cable direction, so it could go left and then up and over.  Then I manipulated the cover plate and screwed it in. I screwed in the last mounting bracket screw(right)to complete install. The ice-maker when done, looks good and you won't really notice the cable off to the left unless you are looking for it.  The other reviewers are spot on when they say this ice-maker is less efficient, because it is.  In my case, my older ice-maker made 8 cubes per batch, this one does 7 cubes per batch.  All in all a good buy, if you can handle a bit of puzzle solving!  Hope this helps other DIY'ers out there with the same problem.
