Anyone have experience with this set up.
Thanks.

That's pretty easy to do. Just feed the buzzer through a 555 timer circuit. Adjust the timer for, say, a 10 second delay and the buzzer will then have 12v positive (but no ground) after 10 seconds. Then, if you lose
oil pressure, the sender will provide the ground circuit to the buzzer and it will sound off. 555 timer circuits are really cheap. Here's one place to get them for about $15.
