On the back of the speedo you shoud see a connector that is part of the membrane circuit that connects all the various gauges, lights together. This connector has 6 membrane tracks which connect to the BoD circuit in the speedo housing. Remove the top cover and have a look at the rear of the speedo. If you see the connections (a section of plastic membrane track) in the centre of the speedo then you have a BoD.

Lol, the BoD is an electronic circuit board with a small buzzer - it is fitted in the speedo.
