Barry,
Your way sounds very reliable. And I already have a couple of relays...
I was thinking of using a transistor to invert the function of the oil
pressure light and drive a single relay. It would probably cost more than
two relays just to isolate and protect the transistor from the unfriendly
electrical system.
