<VV> Oil pressure sender for the dash light

[Stephen Upham]

I've been thinking about this problem, and here is my take. The  
original sender switch for the dash light works like this.  When  
there is no pressure, the sender is grounded and the light comes on.   
As the pressure increases during startup, the sender looses ground  
and the light goes off.
On the sender from Cal, the opposite happens.  When there is no  
pressure, the sender breaks ground and no electricity is fed to the  
fuel pump.  As pressure increases during startup, the ground is made  
and electricity flows to the fuel pump.

In that case, I would not be able to use the shutoff sender to work  
the dash light.

Now, if I'm correct in my examination of this circuitry, is my  
solution the Vega type sender, and if so, what year model Vega will I  
ask for when the inevitable question of "what's the make and model"  
of the car comes up at the local FLAPS?
