Soundz like two seperate issues there.. Check the relay under the drivers side front speaker for the cdl, power any clicking sounds..

Rev counter could be many things. Start with checking the plug on the back of the clocks.

post your progress.

Can't see any obvious connection between the two. They both use the same earthing point (above glovebox), but so do lots of other things.
Locking is fuse 28.
Instruments are fuses 21, 10, 12.
Tacho could be one of the first signs of SI board problems within the cluster, but I've found tacho's very sensitive to a poor connection on pin 9 of the bulkhead mounted C101 engine loom plug.
For the central locking, dig out the locking ECU from below the driver's footwell loudspeaker, and check, with a 12V 5W or 21W lamp (NOT a meter) for 12V across the red/black and the brown wires, then post again.
