I recently purchased a 2007 S80. The seats had some marks on them so I acquired front and rear seats out of a doner 2008 T6. My S80 did not have the heated seats option, and the T6 had the enviornmental package and optional rear heated seats, so now my seats have the ability to be heated if I can get them wired. I've spoken to a dealership, well, they are helpful but really have no idea where to start.
What I'm looking for is a parts list (need access to a dealer service manual). I can do the work myself, just need someone in the know to get me started.
Any thoughts appreciated.

 

Most of the wiring for the seat should already exist, you'll just need a new climate unit (I'm trying to remember where the controls are on a 2007) with these buttons. You'll also need to have the feature enabled by the dealership, it will not just work if you plug it all in.
