The green/yellow wire from the speed sensor is what sends the signal to the cluster and ECU. It needs to go to the green/black wire at pin 2 of the 10 pin connector going into the 04 STI cluster(if you're using instrument cluster wiring from the 02 WRX, the wire is in the same location but it is green/yellow).

That same wire has to be T'd off to also go to the VSS input to the ECU.

The Black/Red wire at the VSS is ground and Green/Black power.
