Does anyone know where BLU/BRN and BLU/RED wires lead in a 1986 735i? The wires are located behind the right front speaker. Where the Motronic control module is. This would be some great help. It's like the wires just grew there, and none of my diagrams indicate a BLU/BRN wire. Maybe I'm not seeing it. I don't know. Help!
