Hello everyone I am in need of some advice/help. I have a 2016.5 Model S with 2nd Gen seats. I recently purchased the 4th Gen (Tesla Premium) seats and went to install them yesterday. The drivers seat switched over fine except the memory location, seat heater, and power headrest won’t work. As for the passenger seat, the new seat has three wiring harnesses and my car only has two available for connection. Due to the fact that there is still a harness that is not connected, the seat won’t move at all. Is there some sort of adapter I can purchase to turn the three seat harnesses into the two that my car has or is it possible to swap the wiring harnesses out of my old 2nd Gen seat to this new 4th Gen seat? I appreciate any and all help as I’m very desperate and love the new seats. Thanks!!
