Fluid level sensor. You either have an aftermarket radiator that is consolidated to cover many configurations that might include features you do not have, or you have a used radiator out of a GTA with digital dash.

That looks awfully low in the side tank to be a fluid level sensor. Shouldn't it be up higher in the driver's side tank near the upper radiator hose?
