Hoping someone on here has some insight, I'm considering trying to retrofit rear heated seats in the Panamera and I'd like to use factory wiring if possible. So the question I have is are all Panameras wired the same from the factory and maybe just don't have certain things populated?

For example if I was able to secure the wiring harness for the rear controls, would there be a port there that I could simply plug the new to me harness into?
