The stripping section is a round hole near the handle of the tool. The sheathing should come off cleanly, leaving the wires exposed.

Cut off the small plastic wire separator or core so it’s out of the way. Don’t cut off or remove any of the wires or you won’t be able to crimp them into the connector.

There are 8 wires in total that need to be arranged in the right sequence. Note that the wires labeled Orange/White or Brown/White indicate the small wires that have 2 colors.

The cutting section of the tool will resemble wire cutters. The wires must be in an even line to be crimped into the RJ-45 connector properly. If you cut them in an uneven line, move further down the wires and cut them again.

The sheathing of the cable should fit just inside of the connector so it’s past the base. If any of the small wires bend or don’t fit into a groove correctly, take the cable out and straighten the wires with your fingers before trying again. The wires must be inserted in the correct order and each wire must fit into a groove before you crimp the connector.

The crimping tool pushes small pins in the grooves down onto the wires to hold and connect them to the RJ-45 connector.

If any of the pins aren’t pushed down, put the wire back into the crimping tool and crimp it again.

Don’t cut too deep when you make your initial incision.

Some of the wires have 2 colors on them, like the orange and white wire.

The wires need to be even in order to fit into the grooves in the connector. If you cut the wires unevenly, move further down and cut them again so their ends are in a straight line.

Be careful not to crack or break the plastic connector.

Lightly shake the cable and listen for any rattling that could indicate that one of the pins isn’t secure.
