what kind of wire would i need to do this and where can i buy it from locally like office max lowes or walmart or radioshack..
Pretty much any wire will do. Radio Shack calls it "hookup wire". A number of folks around here recommend
cat 5 ethernet cable (that's 24awg by the way). Office Max should have that. I couldn't find anything on Lowes.com, but I'd be surprised if they didn't have something you could use.
also whats the difference between 18wg and 22wg gauge wire? is one better the the other?
The difference between 18 and 22
gauge is the diameter. Neither is better, but the more electricity you're going to feed a wire, the larger (lower gauge) you want it to be. The thicker the wire, the harder it is to bend, and the more expensive it is because copper isn't cheap.
speaking of the wire what it look like?
What does wire look like? It's long and skinny. Usually it's copper in the middle and has a plastic or other non-conductive jacket on it. It comes rolled up on a spool so that you can fit 100' feet of it in your car without poking anyones eye out. I have provided a picture of wire on a spool and another wire ready for action.
