Ronnie --
Here's a diagram...

As Randall notes, there are 3-terminal relays in the world -- I use one on
my brake lights but that works because I am controlling power. As you can
see in the diagram OD switch controls the ground side of the equation.
If interested I have versions of that diagram wherein I have added the
diode suggested (elsewhere) by Randall. I also added a fuse and indicator
light but all this can come later after you have the thing working.
