Yes you can add power windows and yes it will be a direct swap. All you need are 98-02 Accord LX or EX power window parts and swap them on. It would be easier to just buy the driver and passenger doors for those not mechanically inclined. But yes IT IS a direct swap, you have plugs in your cars wiring hiring harness that will connect to the power window plugs. I've did it to my Civic so I'm telling you from experience.
