Do you still have the blue ribbon in the gauge cluster or do you have the
new improved version?

I don't know about the new improved version but with the blue ribbon please
check the flat 14 pin connectors to see if it's damaged or not or doesn't
have a good connection. The pins #12 and #13 are for oil pressure and the
#6 is for the coolant. If the thin copper strips were damaged you can
repair them with copper foil tape repair (do not use soldering iron).

good luck
