I've been helping my pal with his 88 325i. Nothing on the central locking system works. Nothing. We've torn apart the driver door and the driver kick panel, and found some wires with plugs that aren't attached to anything AND don't mate with anything. I'd love to see a picture and diagram of what a working system's wires look like in those areas. Someone previous to us butchered the wiring on this car in many places. Also, what does the main controller box look like for this central locking?
