<VV> Oil pressure gauge and shut off switch setup

[AeroNed at aol.com]

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).

I think  I may have miscalculated the number of plumbs that I need in   
installing a sender for an oil pressure gauge.  Here is the  skinny.   
I ordered an oil pressure shutoff switch from Cal for  the electric  
fuel pump.  I attached the sender for a dial gauge  on an improvised  
line using brake line tubing and a grease gun hose  to the sender for  
the gauge to move it to the pinch weld near the  battery.  I t'ed the  
shut off sender for the fuel pump to  this.  I didn't get a plumbing  
connection that would allow for  two senders (original and the shutoff  
version).   On the  shutoff version from Cal, there are two poles.   
One is for the  power (to battery) and the other to the fuel pump  
power wire.   My oil pressure sender (the one that will actually give  
the pressure  readings) has a ground terminal and a sensor terminal  
that goes to  the gauge under the dash.  Is it possible to run the  
original  sender wire to one of these terminals and get the same  
effect as the  original, lighting the dash light (idiot light) before  
turning the  engine over?
