First open the bonnet and under the wiper mechanism you will see a white tube. There follow the cable... It goes down to the shifter... You need a 15 or 17 key... Release it from there...
Remove the dash, two bolts up, one behind the cover in the small zone.
4 screws holds the instrument cluster... Pull back the cluster, remove the black and white connectors and then remove the Speedo cable... Voila
