Every manufacturer has their own way of connecting the various electrical=
=20
devices in a gas tank.  I'm not directly familiar with the Olds Cutlass, =
but=20
for a 1980's-era american car, you should have a ground line, +12V line, =
and=20
a resistive-output line from the sender.

Be absolutely careful with any electrical experimentation around a fuel=20
tank!!!  Especially when empty!!!  A common trick is to fill it with wate=
r=20
first, but I'd still be paranoid!!!  I highly advocate that you contact=20
Oldsmobile instead, or buy the proper wiring diagram/manual!!!

The exclamation marks are not to shout at you, but to express how strongl=
y I=20
feel about working on or near a fuel tank.
