1) Where is the oil pressure switch for the 60x and 61x engine which gives a contact closure for no/low oil pressure. 61x engine is non electrical, I think.
2) Would it sound during start up? It would during start up and shut off, right.
3) I am also thinking about adding in a vacuum relay to tie in with the shut off valve to cut off the engine fuel supply. If I do this then I need to delay the activation during start up.

Any info is appreciated.
