Question Need help: installing digital speedometer and tach

Hi All,
I've done a search already and couldn't find a lot of info on this. I'm trying to find the wire that feeds the ECU, on a 2003 WRX, with speed signals and the rev signals. Also the wires that feed 12V power and ground. The reason being I'm trying to install a VSD Basis, digital speedometer and rpm gauge. Any pictures, info, coloring on the wires would greatly be appreciated. Thanks

So what where the name of the pinout you had to connect to for the tach?? Was it engine speed sensor? Or throttle position?
