I purchased a 25 foot extension cord. Make sure that the extension cord has all three plugs on it. You'll want to have the grounding action for most applications. I simply removed the "female" end of the cord, for those of you who don't know what that means, it's the end that doesn't plug into the wall. Make sure that the cord isn't plugged into the wall. I then removed approximately two inches of outer insulation, and then stripped away just over 1/2 inch of insulation from each of the three wires.

Bend the end of the wires into a little hook, and use the appropriate screw to connect them to the outlet. The green (sometimes bare copper) wire is the grounding wire, and should be connected to the green screw on the outlet. The two wires left, which will probably be black and white, are the 'hot' and 'neutral' wires respectively. The back of the outlet should say right on it which screws are which. Connect the black and white wires using the appropriate screws.

Oh yeah, make sure that you have fed the end of the cord through the junction box before you start connecting the wires (picture 2), or else you'll have to do it all over again :- )
