Low Oil Presure Buzzer

OK, I think I will put it just before the buzzer. That way I can still have the red light work until presure builds up. Great!
Thanks.

Yep, if the idiot light is fed from before the timer, and the buzzer is fed after the timer, I think you'll have just what you want.

For a little bit more you can buy a 3 second 12v time delay relay.

A far simpler way is to run the red wire of the buzzer to the alternator warning lamp wire at the alternator, the black wire to the oil pressure switch wire.

Key on not running, gives you zero volts at the alternator warning wire hence the alt warning lamp is on, oil buzzer will be off.

Engine running with oil pressure, 12 volt at the alt warning wire, alt lamp off, no earth at the oil pressure switch, buzzer off.

Engine running no oil pressure, 12 volt at the alt warning wire, earth at the oil pressure switch, buzzer on.
