Figure 3-14. Our solder is cooling while being held in place with
the third hand.
Now it’s time to insulate our connection. For that step, we will
need our 1/8-inch heat-shrink tubing and a heat gun (or hair
dryer if you don’t have one). Cut three 1/2-inch sections of heat
shrink and loosely
fit them over your newly soldered bullet con-
nections. You want to place the heat shrink across the back
raised portion of the connector, as the front male plug part will
be inserted into the female plug (see Figure 3-15). If we have
heat shrink blocking the connection, it can lead to an unreliable
plug. Feel free to plug the male and female plugs into each other
a few times and take note of where the connections take place.
This will help you better understand where you should—and,
more important, should not—have heat shrink placed over your
connection.
