Product review (5 stars): Great Replacement!
Great product that installed easy and works fantastic!  This version does not come with the wiring harness and that is a good thing.  Just use the existing wires and installation is a snap.  3 bolts/screw hold the entire unit in place.  The hardest part was cutting the water inlet which is basically a small funnel on the back of the unit.  You can use a utility knife or X-acto type knife and the area to cut is outlined from the factory depending on the application.  Instructions were not very helpful, but installation is very simple and there are numerous videos on the net if you get stuck.  I only regret not getting this sooner as I would have avoided a lot of aggravation and frozen bricks in the ice dispenser.  Now I have too much ice and have to turn it off periodically as it makes more than I use.
