2000 Sebring seat wiring question.

I read the artical where the fellow put these seats in a Corvair but they were from 99 and older. He did say to use the Box and Harness from an early car on the 2000 seats but my question is... do I need to do anything else? is it a "Plug and Play" with the seats I already have for the Car ? I hope one of you can help. Any input is welcome. Thanks, Tim
