I have the wire harness that is set up for all that, it came out of an svt. The seat plugs were cut off for some reason as well as the connection to the hatch. I'd sell it SUPER CHEAP if you feel like finding new plugs for the seats and just splicing in your existing hatch wiring.
Other than that it should be plug n play.
