This table provides the standard Lucas wire colour codes used in Series Land Rovers (British Standard BS-AU7 determines colour coding of automobile wiring). I have added the Lucas codes for accessories that might be added to a series Land Rover, such as rear fog lamps, a rear window wiper and washer, driving lamps, radio and electric fan.
Please note that Land Rovers built to military specifications use a different wire colour code.
