How to Change a LAN Crimp End

  • Take the cable, run the knife around the cable, and the jacket should slide off easily.


  • There will be 4 pairs of twisted wires exposed, each of them a different color or color combination.
  • Orange-White striped and solid orange.
    Green-White striped and solid green.
    Blue-White striped and solid blue.
    Brown-White striped and solid brown.
  • Fold each pair of wires backwards to expose the car of the cable.
  • Cut off the core and discard.
  • Straight the twisted wires.
  • Arrange the untwisted wires in a row, placing them into the position, running from right to left, in which they will go into the RJ-45 connector.
  • Orange with a white stripe.

  • Trim the untwisted wires to a suitable length by holding the RJ-45 connector next to the wires.
  • The insulation on the cable should be just inside the bottom of the RJ-45 connector.
  • The wires should be trimmed so that they line up evenly with the top of the RJ-45 connector.
  • Insert the wires into RJ-45 connector, making sure that they stay aligned and each color goes into its appropriate channel.


  • Make sure that each wire goes all the way to the top of the RJ-45 connector.
  • If you dont make these checks, you will find that your newly crimped RJ-45 connector is useless.
  • Use the crimping tool to crimp the RJ-45 connector to the cable by pressing the jacket and cable into the connector so that the wedge at the bottom of the connector is pressed into the jacket.



  • Use a cable tester to assure that your cable is working properly when both ends are crimped.
