I have found the correct bits to turn this on with the older unit, but not with the newer one. If I can get some more newer eprom dumps I may be able to reverse engineer it though.

You can tell the old unit from the newer by the color of the connector on the back. the older unit is Black, White and Blue. The 99 and 2000 should both be the older unit, so you are in luck.
Great! I bought the 996 cluster for $150 because it has a defective LCD. The oil sending unit was $83, so all in all I will be $233 into it. I may as well do the OBC add on at the same time I have the cluster out.

I will send you both of my EEPROM dumps if you have any interest. Both are the older style. I also don't know the specs of the donor 996.
