Cut through the cord just below the plug using wire cutters. Starting at the cut end, slice down and remove about an inch of the cord's jacket, using wire cutters or a utility knife. You will see two or three wires, depending on whether your extension cord has a ground wire. Use wire strippers to strip and expose the ends of these wires, removing about a 1/2 inch of the jackets.
Open your replacement plug. You will see two or three terminal screws, depending on the ground wire. Loosen these screws but do not remove them. If you have the plug in which the outer cover slides down and off the plug, place the cable through the cover before connecting the cable to the screws.
Take the black wire and bend the exposed end around the brass screw. Tighten the screw. Use needle-nose pliers to bend the wire clockwise around the screw so when you tighten the screw the wire moves with the screw helping to secure it.
Take the white wire and wrap the exposed end around the silver screw. Tighten the screw.
Wrap the exposed end of the green wire around the green screw and tighten the screw, if your cord has a ground wire. All wires must be secure and completely underneath the terminal screws.
Close and secure the cover on your replacement plug. Test your extension cord.
