Thanks guys...Yeah, the speedo shop that's looking at my cluster said he couldn't get one, but I thought maybe I'd get lucky on here. Evidently it's even more difficult to cross reference the parts even if he does identify the failure.

Particlewave, I checked everything from the battery to the pins on the connectors, including ground continuity, and everything was perfect. The speedo shop was able to confirm 100% that there's an issue within the cluster, as he duplicated the issue on his bench. He believes something is swapping between power and ground, causing the flashing.

78F350, thanks for the kind offer of the diagram. As mentioned, it's the diagram for the cluster IC board that I need. I guess Porsche would prefer folks to buy a new cluster at $2,600, 25% of the value of the car itself!!

Thanks everyone for the help! I'll let everyone know the outcome. Hopefully I can avoid buying a used cluster. I wonder if just the board itself is available somewhere?
