yeah, let us know which seats you are getting. If they are the dual power with the controls in the center (infamous AL7 seats) then you'll need the wiring that goes under the carpet as well. If they are just the dual power on the side of the seats, you might need the wires if yours were not power before. Might be a little more work if you had a bench. For the rear seat, that is very easy, bottom comes out no tools required and the back requires 2 nuts and 2 pseudo nuts to come off, can't remember sizes right now and then there are 2 plastic push pieces on either side of the pass through inside the trunk and then it just lifts out.
Let us know when you know more about them
