If they are from the same year ( or close) car then they should bolt right in. One some cars, the wiring may even already be there, tucked under the seat or carpet. Most cars usually used the same wiring harness and some plugs just weren't used if the car was not equipped with certain options. Take a look once you get the old seats out. You might get lucky.
If not, then you will have to run a power wire from the fuse panel to the new seats and a ground wire to the seat frame bolt or other metal spot in the car.
