Cut a section of black and red wire to go from the pickup to the volume control. Strip 3/8 inches of insulation off the ends of both wires.
Wrap one end of the red wire around the positive terminal on the pickup and solder the connection. The positive terminal may be marked with a "+" and/or painted red. This is done by holding the pickup with needle-nose pliers and touching the tip of the soldering iron to the connection. Once the connection is hot, push rosin-core solder onto the wires until it melts, completely covering the connection. Allow to cool for several minutes.
Wrap the black wire around the negative terminal of the pickup and solder the connection. The negative terminal is marked with a "-" and is silver in color.
Wrap the other end of the red wire around the input terminal of the volume control and solder the connection.
Wrap the other end of the black wire around the ground terminal on the volume control and solder the connection.
Cut two sections of black and green wire to go from the output jack to the volume control. Strip 3/8 inches of insulation off both ends of each wire.
Wrap the black wire around the negative terminal on the jack and solder the connection. Wrap the green wire around the positive terminal on the jack and solder the connection.
Wrap the other end of the green wire around the output terminal on the volume control and solder the connection. The output terminal is typically marked "2" and is in the middle of the volume control. Wrap the black wire around the ground terminal of the volume control and solder the connection. The ground terminal is marker with a "-". Consult the manufacture's owner's manual if you are having difficulty determining the correct terminals.
Cut another section of black and red wire to go from the tone control to the volume control. Strip 3/8 inches of insulation off both ends of the wire.
Wrap the red wire around the positive terminal on the tone control and solder the connection. Wrap the black wire around the ground terminal on the tone control and solder the connection.
Wrap the other end of the red wire around the input terminal of the volume control and solder the connection. Wrap the other end of the black wire around the ground terminal on the volume control and solder the connection.
