Product review (5 stars): Some Research Required
This product is offered by a number of sellers, some of which change from time to time.  The shutoff arm on models pictured generally differed from the one on my original ice maker, so I was sure I needed a kit with a shutoff arm.  I purchased a Whirlpool ECKMF94 from my local Lowe's at a great price.  The kit included not only the shutoff arm, but also an ice bucket, water valve, plastic tubing, and wiring harness.  Unfortunately, the wiring harness did not fit my refrigerator.  I needed a wiring harness with a round four-pronged plug.  That's when I turned to amazon.com, and found this product.

I contacted the two sellers with the lowest delivered prices to verify components included.  Both verified the kit contained the shutoff arm and the round plug.  Partshouse asked me to supply my refrigerator model number, and then suggested this product.  Seneca River Trading carries this product, but did not offer it as a suggested replacement.  They did say ECKMF94 was not a suitable substitute.  I ordered the kit from partshouse, and it came with everything pictured.

I was disappointed with the instructions included, but I had viewed a couple of online videos and followed those instructions.  Installation was quick and easy, and just as described in the videos.  Much sooner than expected, based on some the reviews posted here, the ice maker began producing ice, and is working great.  My old ice maker had an option for two sizes of cubes.  This one only produces one size--but at least we have ice--and plenty of it.
