One wire is a ground (earth) the other is the sender wire to gauge.
If you ground the sender wire, gauge should go to empty, or close to it.
The sender sends a resistance number in ohms to the gauge, for example 0 ohms would be empty, 90 ohms would be full.
The problem would be finding a replacement, if Toyota has one, it is most likely not cheap.
