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

Now this is really sad ... but I'm answering my own question ....
I just found the info I need on:

My question to anyone who has done this, would be is it OK to use the "ignition switch" as my 12V live? ...

 

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