Ice Maker was not running

I removed the screws and pulled the unit out a few inches. The wiring harness was difficult to disconnect since I did not know how it was being held in place. Once I did get it disconnected I saw there was a tab that had to be depressed. There was an access hole for depressing the tab but I did not see it until I had the unit removed. The instructions only say disconnect the harness, but not how. So I learned the hard way, damaging the harness.
