Interior swap - help needed

[Astroboy]

What's up guys, did anybody swap 4.6is seats [front and rear] onto newer X?
I'm going to check them out on Sunday and since these seats were made in 2002 for '03 4.6is and I got refreshed '04 model Im a little worried
Is wiring harness the same in both models? Also that would be an upgrade from none heated to heated seats. Is it just a matter of getting switches in place because all the wiring is there, or maybe there is more to it????
What to expect... what to be aware of????

I did that interior swap today, it took few hours but came out better than I expected. All the harness were plug and play, even the rear [3.0i] was prewired for heated seats, Seats are used to have are being sold if anybody needs them, they are mint
