Found these to give you an idea. Seems there is two ways
1. is for Cars that use a separate Sensor for the Speedometer
2. is for Cars that use a ECU output for the Speedometer.
Right 3 possible points from what I can make out
The ECU
Behind the speedo cluster
Or you have to fit the converter on the wiring above the speed sensor on the gearbox :D
I'm just not sure which one it is. Had a look on Fleebay only kits I could find was all to do with the classic shape Imprezas
But THIS is what I was on about from HKS
If I remember you have to take the speedo cluster out and bridge it,but if not already done would give you the chance to change the Speedo to MPH. It was the case with older Impreza's anyway not sure if it's all done from the ECU now. I will have a look :D
Ok it is all done from the ECU by the looks of it. But the cluster trick changes it to MPH and moves the limiter to 180MPH which you wouldn't be able to do anyway. I think you can buy the kits to do them on ebay. But I'm sure likelihood is you will have stuff at home that will do the same thing.
