Decide the Best Placement

Decide where the best place to install the jack is. The location should be easily accessible, well protected from damage, and free from extreme dampness and heat.

Let’s start from the very beginning

Find the phone interface box that is mounted on an outside wall. Open the customer access panel. Unplug the test jack. If you have an older interface boxes, it might not have a test jack. Just unscrew and detach the wires. Make sure you will not forget which wire that went on each terminal. If you are not confident enough to access the interface box, use another phone on the same line and off the hook.

Make sure the line has no dial tone and unplug it from the jack. Remove the jack and check carefully which colored wires hooked up to the terminals. Match the wire with the new jack.

There are two wires that are required for a phone, and each of them contains at least four wires for additional lines. The colors are red and green for the first line. Yellow and black are for the second line. Blue and white are for the third line.

After removing the wires, attach them to the new jack. You will see the stripped ends of the wires appear brittle. Then cut off the damaged wire. Strip the outer insulation around the line back two inches. Do not nick the wires.
Cut back 0.5 inches to 0.75 inches of the insulation. Bend the exposed wire into a “U” shape. Slip the wire over the corresponding terminal on the jack. Wraps the wire around the terminal in a clockwise direction and tighten the screws.

Attach the new jack to the wall. Reconnect the phone line at the interface box. The next step, plug the phone back in.
