I have seen several threads about the 04 - 05 cars having ribbon cables for the mirrors and not being able to use the M3 mirrors. Some of those threads said that the early production 04 cars still used the standard 12 pin wire connector and that those cars could use M3 mirrors. Does anyone know when in 04 production BMW went from the 12 pin connector to the ribbon cable? I have an 04 with and 11/03 build date. I am hoping my car uses the 12 pin connector so I can install ///M mirrors. I don't really want to take off the door panel to check unless I have to. Thanks!
