How do I wire a rheostat?

[Crazy Jayhawk]

I picked up a rheostat at Radio Shack and I'm not sure how to wire it.

My cheap-o rendering of it, looking down on it from the knob side. Where do I connect the 12V line and how do I connect the fan to this apparatus?

Look at the rheostat in this picture. I think it will help you out.

No matter what I do, the fan speed never changes. There are thee ways to connect the wires to the rheostat. I've tried all three, and none of them did anything.

Help!

Just out of curiousity, do you have the fan wired correctly? Make sure the fan molex is wired for 12v and the rheostat is wired to the yellow 12v lead.
