03 Corolla CE - Adding power windows

I would like to go to my local wrecking yard and pick up everything needed to add power windows to my gf's 2003 Corolla CE. I need to know whether or not the car will already have all the wiring just sitting there and just not hooked up. By wiring, I mean the power wire, the wire which runs from the driver's side to the passenger side for the driver's master switch to control the passenger window, etc... I'd imagine that it would all be there but just not plugged into anything right now? Can anyone shed some light on this for me?

Thanks.
