Found the VSS wire for the 2002 Tundra Extended cab, automatic, V8. IT IS the Green/Orange as I was told above - thanks! Good news - it runs thru a junction box, J7, directly behind and to the left of the radio cluster - back on the firewall. So - didn't have to putz with the instrument cluster. It is also on the ECM, plug E4 (second from the left), behind the glove box, pin 5. Hope this helps the next guy!
