o.k. well I found it...cost me 20 bucks but on the audi it's called VSS (Vehicle Speed Sensor) and it's located on the wires coming out of the back of the Tach and it's the green wire with a red stripe. I needed to find this wire cause I just bought a pioneer AVIC-N1 and it required to be connected with that wire.
