lots of great info on here!!! I'm completely non tech when it comes to programming and stuff like that. Got a question tho. If I have 2 front seats out of a 2015 with heated and ventilation wires and all still good and installing them in an 2008 ( got the brackets & power figured out ) do I still need one of them LIN systems to make these work with the stick switches? I can see the wires run to small module but don't know what wire does what.
