<VV> Which Gauge?

[jimster1]

When I redid my dash with all VDO instruments I installed a screechingly
loud piezo warning buzzer.  It will sound off if either idiot light
illuminates.  I wired mine using the oil pressure switch that has both N\O
and N\C contacts.  This way the circuit is only active after the engine
starts and the oil pressure is up.  A latching relay keeps the circuit alive
in the event that the oil pressure goes away.  The oil pressure switch
prevents the buzzer from burning your ear each time you start the engine.

It would be a good idea not only to have gauges and warning lights, but also
wire in a warning buzzer as well. That way you can hear of the impending
disaster before you notice the warning lights or gauges and you have your
hands full trying to control the chaos...
