Fuel Gauge reads empty all the time

Question

I have removed the tank and checked both fuel level sensors and while assembling the tank and electrical connection noticed that there are ten wires coming from the tank while there are only nine pins connected to the body harness. The blue wire comes from the fuel sensors but ends at the connector. I am looking for a wiring diagram for my 2006 Pontiac Torrent that shows the wiring from the tank to the gauge.
Can you help?
