There are two product metafields definitions required to connect each of the products together and generate linked swatches.  

Using the Shopify Admin, choose **Settings** -> **Custom data** -> **Products**

Both metafields will be defined under the category of **Products**

Choose the **Add definition** button. If this is your first time creating a metafield, the options may look similar to this, simply click on one of the Add definition buttons:
