Dash plugs (speedometer, fuel guage, etc...)

[HITNRUN]

I have a 90 TSi AWD. The gauge cluster plugs into the dash as a unit. My fuel gauge stopped working. I'm wondering if anyone has a diagram that tells what pin in each plug runs what gauge. I want to see if there is a signal getting to my fuel gauge. But I'm not sure wich pin comes from the sending unit. Thanks guys.

This is the back of the gauge cluster. The yellow circles are where the pins are that plug into the dash in the car. Does anyone know which pin sends a signal to the fuel guage. Thanks.
