As far as I can tell, there is no tacho wire as in pre-computer cars.

I may be wrong but it looks to me that engine revs are send to the display board as serial data from the ECU. On the display board it seems this information it is converted to drive signals for a servo motor with the tacho needle pushed onto the shaft.

Perhaps there is a auto-electrician on here who can confirm.
