So i might have missed the solution in another thread but I'm trying to install a new HU and all the wiring diagrams for 2004 Z4 business radio I can find say that all ports have wires connected to them. I am missing wires in ports 1, 4, 5, 8, and 11 and do not have connectors for slot B or C. Do I have a different system set up or am I missing wires? Do I need to buy a special adapter and if so, where can I find one? I attached photos for visual help as well.
