Im currently in the process of installing an electronic Mopar Ignition in my 72 Dart(it currently has a 1976 225 with points,go figure)

Im looking in my Older Haynes Manual and notice something that puzzles me. Hoping someone could decipher this for me. In the image its highlighted in Blue.

What does this mean?
