Apple flex cable drawing archive for the HDD-BT flex, part 821-0403, schematic 051-6959 at revision code 04000, labelled M1. The 217 KB RAR presumably holds a short schematic showing pinout and routing for the hard drive and Bluetooth connection cable. Apple uses 821- part numbers for cables. Technicians use such documents to test continuity pin by pin, find open lines and verify which rails reach the drive and wireless module before replacing the cable.
