I installed replacement ice maker. Overall the installation was fairly simple, 3 screws and a wire harness that needed connecting. However, the instructions could have been clearer. For example, they did not make clear there was a plastic tab that needed to be removed to make room for the water hose feeding the icemaker. It also never showed or mentioned a plastic bracket that needed to be attached to the ice maker so it could be attached to the fridge wall. It was good I still had the older nonfunctioning ice maker so I could see how everything went together.
