Hi, I'm looking for some advice on retrofitting heated seats to a 2016 f22 218i. The car currently has non heated fabric seats. I understand I need to get the heated seats with control modules as well as the AC unit with heated seat buttons. I also understand these need to be coded in. What I'm unsure on is if there is any wiring required between the seats and the car or if this is simply a case of plug and play?
