There is one wire that splits into two wires and connects to the little plastic housing connecter that plugs into the radiator level sensor for the expansion tank on the bottom. Normally there is some kind of wire casing but in this instance there is not since the car is used. I'm guessing this is how one of the wires snapped in the first place. I need to know what this wire is called so I can order the part. Any help would be appreciated.
