<VV> Oil pressure gauge and shut off switch setup

[Dave Thompson]

Steve,
I'm sure that you know but I'll tell you anyway. The threaded body of the
switch will be grounded to the engine when installed. One terminal switches
to ground without pressure. When you apply pressure, That terminal is
removed from ground and the other terminal is switched to ground. The sender
switches ground, or "sends ground".

I think that you have one more terminal than I do.  My switch (the  
shutoff from Cal) only has two.  The "off with pressure" apparently  
is not a terminal that I will find a connection for on the switch  
from Cal or the sender for the gauge.   I'm getting the sinking  
feeling that I'm about to buy another pressure switch; the Vega type.

Yup, that's how mine is wired. One terminal is ground, one is "on" with
pressure (that goes to the fuel pump) and the other is off with  
pressure (that
  one goes to the dash light).
