Audible low oil pressure warning?

[RedBarchetta]

I'm finally getting around to hard wiring my low oil pressure sensor. I was going to just tap an existing warning light on my factory SPF dash (i.e. bad alternator), as I wasn't really wanting to start drilling holes into it.

Then I thought about the location of that particular light and how my left hand typically blocks it when I have it at the 9-10 o-clock position on the wheel. I also started to question why I would want a light to get my attention, especially if in the middle of a bright afternoon when it sometimes requires a squint to see the needles on the gauges? A loud SOUND would be better.

So I'm going to go with an audible warning instead. Found some 12v piezo buzzers at Radio Shack, one being a high-low siren that pumps out over 102db. I figure that even at WOT I should be able to hear that.

Mounting will also be custom, as I'm going to affix an on/off toggle ahead of the power connection and mount it so that you have to barely reach under the lower edge of the dash to flick it. That way when I'm at the local drive-in, Cars & Coffee meets or gas station and start it up to leave, I won't have this glaring siren going off. Once the car gets above 20psi, then flick the switch and the low oil pressure warning system is "armed."

Thoughts before I begin?
