Might be a grounding issue... Is the cluster seated correctly?

Also any sign of the ABS/Tc lights when it plays up?

Not sure that the relay can hndle the high/low frequency the abs sensor would generate.  You may need to feed the signal through a microcontroller to interpret the feed and produce the correct signal.

Could be an interesting arduino project?

I've had this with my rev counter, randomly will jump about and then it's fine again, very strange but a new cluster is cheap enough on the bay.
