I am assuming this will be the case with the newer 08+ Imprezza's. The 05+ Legacy GT does not have a pseed sensor wire at the ECU. It took me a few days to find it but I finally found all the wires to hook up the AVC-R. You can use the schematics below except for the Speed Sensor wire. The pin locations are correct but the wire colors are not the same. The Speed Sensor wire is located on the instrument cluster. dk green/black in pin 19, green plug on left hand side of cluster (as if you are looking at it from the drivers seat) I hope this helps any future AVC-R installs.
