Ah.

So if I keep it as is, I have to "live with" the chirping?

(I'm too cheep to buy the extra part ..... pun intended)

Actually I'm just not sure how to harvest and install the oil pressure
logic board from an appropriate Vanagon cluster.

Maybe the Jetta cluster has it? I also have an '85 Vanagon cluster.

Thanks,

Neil.
