New Oil Pressure Guage

["Brubaker, John" <JBrubaker@AMF.com>]

Greetings all,

I went ahead and hooked up a n-used oil pressure guage up to my 80 
Scirocco S and sort of have a problem.  Here's the scenario:

I pulled the guage (kp/cm2 - any Europeans know the conversion to 
PSI's for this one, or simply what the guage "should" read) and sender 
from a 924 Porsche.  I installed the sender into the side of the head 
where the original oil pressure switch was located and attached the 
wire coming from the original switch to the "new" sender (the + 
terminal).  I then ran a wire from the "G" terminal on the new sender 
to the "G" terminal on the new oil pressure guage.  I installed the 
new guage in place of the factory clock right next to the oil temp 
guage.  I then simply attached the + wire and ground wire that was 
attached to the factory clock to the + terminal and ground terminal of 
the new oil pressure guage.

First question:  Is this the proper way to install this (I simply used 
never before seen nor done this logic)?

This is what happens now that I have the new guage hooked up:

It seems that the gauge rises and lowers in direct relation to the 
tach (sort of like a mini-tach).  Also, once the car warms up (over 
175 degrees F), both my oil light and brake light (to the left of the 
tach) come on once the idle drops below 1500 rpms (this did not occur 
before the installation).

A slew of questions:

1)	Is my oil pressure bad?
2)	Does the sender seem faulty?
3)	Is it possible that I have a short in my line somewhere
4)	Any other ideas.

Otherwise the car is running great, thanks for any help.

John
