How to Replace a Phone Jack in a 40 Year Old House
Traditional phone jacks use telephone wiring that runs throughout the house and connects to the main phone line coming in from the street. The wiring used for a phone line has not changed in many years. This means replacing a phone jack in a 40-year-old house is done the same way as a phone jack in any other house. Replace a phone jack in a 40-year-old house by first examining all of the phone jacks in the home.
Remove the screws that are securing the jack plate to the wall or electrical box with the flat head screwdriver. Pull the old telephone jack from the wall.
Examine the wires that are connected to the old jack to see how they are connected. The phone wires will be color-coded.
Unscrew each of the terminals on the back of the telephone jack with the Phillips head screwdriver and pull off the telephone wires.
Set the old telephone jack aside and then cut the ends off of the old telephone wires with the wire cutters. Trim about a ½ inch of insulation from the wires with the wire strippers.
Bend the tips of the electrical wires, with the pliers, and connect them to the terminals on the back of the new telephone jack. Match the color of the telephone wires to the color of the wires on the back of the telephone jack.
Tighten the terminals on the telephone jack with the Phillips head screwdriver. Secure the telephone jack to the wall or electrical outlet with the flat head screwdriver.
