This video will show how to crimp RJ45 connects to either Cat5e or Cat6 network cable. You can find the CAT5/6 crimping tool here. It has an RJ-45 crimping jack, RJ-11 crimping jack, wire stripper, and wire cutter. Briefly, here is how you crimp network cable:
First, strip your network cable using the wire stripper.
Apply gentle pressure and slowly twist the cable. Remove the wire separator from inside the cable if one is present.
Untwist the four pairs of wires and arrange them in the correct order as pictured.
Once the wires are in the correct order, manipulate them into the RJ-45 connector. With the wires arranged evenly, use the RJ45 crimping tool at this time to securely crimp the RJ-45 connector to your Cat5e or Cat6 cable.
Ensure that the wires are all flush to the back of the connector and are all making contact.
Once your wire is crimped, it is always a good idea to test it with a wire continuity tester.
