Product review (4 stars): Replacement part worked perfectly - some tips on replacement
The new icemaker worked great but KEEP your old unit.  The replacement came with no mounting bracket, electrical connections, or instructions.  You will need those from the old unit, plus the mounting screws.  For my fridge, a tab needed to be removed so that the water supply tube could pour into the little catch basin.

To disconnect the electrical connections, pull up on the little tab to get it over the catch.  You can't always see that in a narrow space.

After replacing the old unit with the new, the original problem persisted - water was pouring out of the back and icing up the back of the freezer.  It turned out that the supply tube had been pushed back into the mount, and did not extend all the way into the ice maker catch basin, so some of it ran into the back of the freezer.  After I pulled it out about 5/8 inch (I used a large tap to snag it and pull it out), it extended into the middle of the catch basin and it worked perfectly afterward.  Although it turned out that I didn't really need a new one, the old one was pretty gross anyway (13 years old).  My only complaint was that the electrical connections and instructions were not included.
