Leather Seat Upgrade Wiring Harness

Hi all, I'm looking to upgrade my wife's 2017 Cherokee North edition cloth seats to leather. I am fortunate enough to live with a 40 min drive of about 4 or 5 scap yards that have a good selection on car-part.com. I just need to confirm availability. The question I have is that her current cloth seats are manual with heated, and I think I would want to upgrade to power seats with heated. Is there an existing wire harness that the seat plugs into underneath the carpet? Or do I need to make sure to grab those as well?
