Step 3 Junction box wiring

OK, the worst of it is over. Now you just have to wire up your switch. Pop open the smallest perforated area on the side of the junction box with a screwdriver, and put the cable clamp into place. Cut off the female end of the extension cord, stick your extension cord in and pull thru some slack. Carefully slice open the orange sheathing, taking care not to cut the wires underneath, and expose about 4 or 5 inches of the wire inside. Cut the green wire off (that is your ground, you don't need it for this), and expose about 3/8s of an inch of the copper wire inside the black and white wires. Bring the wires from the first socket into the box via the top opening (with cable clamp already in place) and twist the white ends together and then twist a cap onto them to connect them. Make sure that no copper is exposed outside of the cap. Take the black end of the extension cord and wrap it around the pole on your switch that is closer to the off position, then screw it down tight. Attach the black wire from the first socket to the on pole and tighten it down. Lastly, tighten down the screws on the cable clamp to secure all those wires.
OK, now we are ready to test the thing. Screw in your 100 watt bulbs, plug it in, use a piece of wood to switch it on. and....
