  1. 1

    Strip off an 1/8 inch of insulation from the negative wire and the positive wire. The negative wire is usually black and the positive wire red, green or another colour. Grip the wire with a pair of wire strippers an 1/8 inch from the end of the wire. Pull the insulation towards the end of the wire.

  2. 2

    Identify the positive and negative ends on the input jack. The positive connection is the long tip that touches the guitar or headphone chord when it is plug into the jack, The negative connection or ground is the part of the plug that touches the shaft of the cord when it is plugged in.

  3. 3

    Heat a soldering gun for two to five minutes. Wipe the tip of the soldering gun with a damp sponge to clean the tip and remove oxidation.

  4. 4

    Apply a small bit of solder to the tip of the soldering gun. This process is referred to as "tinning." Hold end of the solder spool to the tip of the gun. Melt a small bit of solder to the tip of the soldering gun. Repeat the process to positive tip of the input jack.

  5. 5

    Hold the positive wire to the positive connection of the input jack using a pair of vice grips. The vice grips prevent you from burning your fingertips. Apply additional solder to the connection. Hold the wire in place several minutes until the soldered connection cools.

  6. 6

    Clean the tip of the soldering iron with a damp sponge. Repeat the tinning and soldering process with the negative wire.
