that wire to the best of my knowledge is to test the relay. it connects to a hot lead to see if the relay or pump is bad... with out power no fuel pump working could be the relay or the pump add power to the wire if fuel pump starts working the relay is bad and the pump is good, add power and its still not pumping fuel pump bad..
