You don't need any special wiring. There's a power and a ground for the seat controls and I believe a power and ground for the lumbar.

Hopefully that will help you some. I'm not 100%, but I'm pretty sure all you need is another +12v for the heat function. I've got '00 Escalade seats I'm wiring in my Suburban which are probably about the same so if I find out anything helpful I'll let you know.
