What is VSS speed sensor wire?
I can tell you that the VSS wire is used specifically for the functionality of the stock radio that raises and lowers the volume dependent on vehicle speed to compensate for road noise.
Where is the VSS?
Automatic Transmission The Vehicle Speed Sensor (VSS) is located on the right side of the transmission near the output shaft.
What is a VSS sensor?

Where is my vehicle speed sensor wire located for?
The other 2 are not used but the VSS wire is the brown wire located on the larger of the 2 connectors not being used. In addition to the standard power and ground leads, remote-mount navigation (and even some in-dash units) systems connect to a vehicle’s Vehicle Speed Sensor (VSS) wire.
Do you need a speed sensor wire for Your Stereo?

How does the speed sensor work on a Toyota?
On at least some modrls Toyota likes to take the analog speed sensor signal fed to the speedometer and convert it (in the speedometer) to digital (square wave) to be sent to the computer. You can intercept the wire coming out of the cluster.
What happens if speed sensor is not connected?
SPEED SENSOR (Green/White) To the vehicle speed pulse line. Improper connection of the speed pulse line may cause important safety features of the vehicle to fail (such as the brakes or air bags). Such failures may result in an accident and loss of life.
