The box that will work best for installing in existing walls has two wings on it that flip up when you turn the screws. You should be able to get these at any good building supply store (figure 21).

Now you will need to run the cable through the box before you install it in the wall. Here is an example that shows a cross section of what it would look like in the wall (figure 22).
Then you will need strip 1 1/2" of the outer shield off the cable. This will expose the 4 pairs of wires that are color-coded. The color code is as follows: Blue & White, Solid Blue; Green & White, Solid Green; Orange & White, Solid Orange; Brown & White and Solid Brown (figure 23)

You will need to use the A color code which is along the top on this module. (figures 24 and 25)
