Hack your House: Run both ethernet and phone over existing Cat-5 cable

Step 7 Remove a pair again

Using a knife, remove a small section of cable jacket as close to the RJ-45 plug as possible.

• Now is not the time to damage wires-- if you do, you will have to crimp on a new RJ-45 plug, which means more money for parts and a second trip to your local networking guru for a crimper. However, if this happens, you can simply not crimp in the brown pair and not have to remove it afterwards. It's still not worth it to re-crimp the ends.

Using side cutters, clip the brown pair close to the plug.

Remove a small section of cable jacket a few inches from the RJ-45 plug, as you did in step 4.

Again, using a small screwdriver, pliers, or a knife if necessary, extract the brown pair so it sticks out from the cable two or three inches from the plug.
