Added a warning buzzer for low oil pressure

The oil pressure in my car has always been great, but I thought it would be nice to have an audible warning in case I lost oil pressure for some reason, so I bought a cheap buzzer on eBay, and with member Afterburner's help and his excellent color electrical drawings, I wired it up today. It works great, comes on as a test tone when you first turn the key on, then goes out when the oil pressure builds above the minimum. I was able to secure it on the back of the gauge package with some heavy duty double stick tape.

Yes it's working just fine! I just wanted an audible signal to go along with the red warning light. In fact, the buzzer is wired into the light itself so they both come on at the same time.
