TIP: It is not mentioned in the video, however, it is recommended to tin your wire connections with solder. This will make the wire ends a little stronger, and it will be less likely to slip off of the screw terminals. Tinning the wire connections is highly recommended. Placing electrical tape over the screw terminals may also prevent: loose screws from falling out, and tension relief on the wires.
