It is a temperature switch. It is used by the ECU for emissions stuff. You don't really need it especially if you have removed the rats nest.

on that same note ... not too hijack a thread ... but where does the wire that attaches to the low coolant level attach ... ever since i've bought my car it was never attached and I couldn't find any loose wires around it.

Look for a loose or even cut wire running around the battery toward the front area. There's a wrapped wire harness hung on the sheetmetal ridge that runs from the coil area behind the light bucket to the radiator. You're looking for a single black wire...
