Low fuel sender

The cluster I put in my car has a low fuel level light on it and I want to make use of it. I was wondering where I could get a low fuel sender. Can I just pick them up at any auto store or are they something that would have to be special ordered? I don't think 92-95 came with OEM low fuel light except maybe the Si's or JDM model's. I know mine doesn't have the wiring, anyways can anyone point me in the right direction?
