No instructions on how or where to install. This only matters because it wasn't an exact replacement for the original part. I must have a different revision of this dishwasher, because this part does not connect to the tine row parts, which are a different shape in my dishwasher. I trusted that since the model codes matched, this would be the correct part. I didn't think I would have to look at every part in the diagram and compare with every part in my dishwasher to make sure the design hadn't changed. I will next time.
