- Trim the wires
Flatten and straighten the wires neatly with your thumb and index fingers then use the cutting blade on your crimping tool to make the end of the wires nice and even - exposed wire should be about half an inch. This makes the crystal fit better and make good contact with the entire surface of the jack's pins.
Insert the wires into the connector
Place the crystal over the wires with the tab side down. Consistency is essential - make sure that everything looks nice and clean, if it doesn't you should start over at Step 3 with a fresh cut.
Crimp the connector
Put the jack into your crimping tool's RJ-45 slot and press down firmly. You won't hear a click or anything like that (unless you have a more-expensive ratcheting crimp tool) but make sure to apply good pressure. Remove and inspect - compare to something that you know works and if it looks good, you're done with that one!
Repeat steps 3-8 for the other end of the cable
- Test the cable
Either substitute the cable into a known-good network connection, or preferably use a UTP or Ethernet cable tester. It's a good idea to give each connector a firm tug before testing, to make sure that the crimp is nice and strong.
