How to Terminate a CAT6 UTP Cable With RJ45 EZ Passthrough Connector

This guide will walk you through a step-by-step process of terminating a CAT6 unshielded twisted pair (UTP) cable using an RJ45 EZ Passthrough connector, including the tools you'll need, wiring standards, and best practices for a clean, functional connection.

1. CAT6 UTP Ethernet cable
2. RJ45 connector (we're using an EZ Passthrough connector)
3. RJ45 end cap
4. RJ45 Crimping tool
5. Wire stripper
6. Scissors or flush cutters
7. Cable tester (optional, but recommended)

Note: We're using the Klein Tools (VDV226-110) crimper/stripper combo

•Install the RJ45 end cap onto the CAT6 cable and move down out of the way.

•Use the wire stripper to remove about 1.5 inches (3-4 cm) of the outer insulation from the CAT6 cable.

•Be careful not to nick the internal wires.

•Remove the plastic jacket and spline inside.

•Untwist the 4 twisted pairs (8 wires total).

•Flatten and straighten each wire as much as possible.

•Arrange the wires in the T568B wiring standard (most commonly used):

•Pin 1– White/Orange

•Pin 2 – Orange

•Pin 3 – White/Green

•Pin 4 – Blue

•Pin 5– White/Blue

•Pin 6 – Green

•Pin 7– White/Brown

•Pin 8 - Brown

•Hold the RJ45 connector with the clip facing down.

•Carefully insert the wires into the connector ensuring:

•Each wire goes into its own channel.

•Wires stay in the correct order.

•The cable jacket is inside the connector far enough for the crimp to grip it.

•Insert the connector into the crimping tool.

•Squeeze the tool firmly to crimp the connector and secure the wires

•Remove the connector and inspect the pins (all 8 pins should be pushed down evenly).

•Slide the RJ45 end cap so that the back of the RJ45 connector fits into the front of the end cap.

•Use a cable tester to verify correct continuity and pinout.

•If the test fails, cut the connector off and repeat the steps.
