The RJ12 cable is manufactured with four and six wires. The four-wire cable is traditionally used for voice transmission with a telephone service, while the six-wire cable is capable of transmitting both voice and data. The six-wire cable is traditionally used to connect networks. Preparing your RJ12 crimp connector cable whether it is six or four wires requires the same steps.

Instructions

  1. 1

    Strip the end of the telephone wire of the plastic outer coating using the modular crimp tool's blade section. The length will range from an eighth to a quarter of an inch.

  2. 2

    Strip the colour wires, one at a time, using the modular crimp tool. To keep from breaking the fine wires, carefully apply pressure when pulling the plastic coating off of the wire.

  3. 3

    Place each wire into the modular plug matching the colours. Push the wire as far as it will go -- be careful to not break the fine wires. Repeat for each colour.

  4. 4

    Crimp the modular plug using the crimping tool. Do not squeeze too hard to keep from breaking the plug.

  5. 5

    Plug your RJ12 connector into the telephone jack and telephone. Or plug the RJ12 six wire into the modem of your computer and other network modules.

Tips and warnings

  • You may choose to use a wire stripping tool rather than the blade section of the crimping tool. Wire stripping tools are made to fit different size and type cabling and telephone lines.
  • Applying too much pressure when crimping the RJ12 connector to the cable will break the plastic.
