Figure out if the fixtures are 2-wire or 3-wire, and buy your extension cord accordingly, strip it, wire nuts, tape, done. Just make sure you cover the stipped portion of the wire completely with the nut, and then tape the connection completely.
That is the key point, if 3 wires are needed then the fixture should be grounded. Most time the grounding is needed if something fails in the fixture and you do not want metal parts having 120V on them and then touching them. Just keep this in mind before you do anything.
Also you do not need extension cord, you just need plug cord and Lowes and Home Depot have this for repairing lamps fixtures. You will also need wire nuts or solder the wire to the fixture. You will also need something thing to secure the wires to the fixture so it will not pull out. Depending on the fixture it may or may not have it own switch if it does that is great, if not then you will need a way to turn the lights on. either install a swtich or get lamp cord with a built in switch.
below are some ideas
