The phone jack in one of my offices is missing. There are four colored wires; green, black, red and yellow. How do I hook them back up?

Dear John:

Most modern phone jacks are pre wired and color-coded. Strip your existing phone wire back about two inches and expose all four wires. (Careful, these wires are very delicate.) Then strip each individual wire about ½ inch. Match your individual phone wires with the color-coded wires in the new phone jack. Loosen each screw in the phone jack and attach the each phone wire by twisting the wire clock-wise around the screw and tighten. Reattach the jack to the wall and you are done. The black and yellow wires are often used for a second phone. The red and green wires are used for single phone applications. You don’t need all four wires to make the phone work.
