compatability of power seats between years

I've got a 2006 E-350 XLT and want to upgrade it to power seats. I think the wireing harness is there, does anyone know if I can just put some power seats in from another econoline? Or will seats from any superduty pick-up fit? I'd rather not have to modify anything, just bolt and plug.

im not sure about the wiring but the seats should fit they make all the holes in the floor for what ever seat the need to put in at the factory. the holes might be under the carpet but they should be there.
