This section of the harness should have a black/white and black/orange wires going from the controller to the fuel pump, a black ground wire, a black/yellow wire that takes power from the fuel pump relay (wire this to the fuel pump power wire in the new car) and purple/white and green/red wires that go to the ECU.
