How To Wire Split Outlets... Step #5: Strip the Wires
In order to attach the wires to the switch, first you must strip the insulation from the wires. Knowing exactly how much insulation to strip off of a conductor is crucial to properly fitting the wire on devices and making a good connection.
Using wire strippers, strip off about 3/4" of insulation off of the black, red and white wires. This will allow enough wire to make the proper connection without having excess hanging out and shorting out against the box.Continue to 6 of 10 below.

How To Wire Split Outlets... Step #6: Remove Hot Tab on the Outlet
There is a tab on the hot wire connection side of the outlet called the hot tab. Locate the side of the outlet where the brass screws are located. Between the two screws and the face of the outlet, you'll notice a small brass piece of metal (called a tab)connecting the hot feeds. Simply break it off by inserting a screwdriver under it and bend it back and forth. You can also use long-nosed pliers to break it loose. Once removed, the common bond is broken.Continue to 7 of 10 below.

The next step is to wire the switch. Starting with the feeder wire, locate the black wire and pigtail it to the black wire going to the outlet and also the bottom brass-colored screw on the switch.
Connect the red wire to the top brass-colored screw on the switch. This connection is what will turn on and off one part of the outlet.
Twist the white wires together and twist a wire nut over them.
Twist the ground wires together and pigtail them to the box and to the green screw on the switch.Continue to 10 of 10 below.

How To Wire Split Outlets... Step #10: Replace the Switch and Cover Plate
When you've finished wiring the switch, you'll need to replace the switch. To do this, screw the two screws mounted on the switch into the two holes mounted on the box. Tighten these screws snugly, but don't over tighten. Now install the cover plate by installing the two screws into the switch screw holes. Be careful not to over tighten these! If you do, the cover may crack.
