KPH to MPH Conversion Wiring

[tooleyrs4]

Hey Guys, 

Happy New Year.

 

I cant for the life of me get my Stagea (Series 2 RS4V Neo Auto) to convert into MPH. I have spent hours researching and each time find different instructions and wire colours. 

Does anyone know what the wires are or have fitted one of these chips? 

From my understanding

I do not have a gey/yellow wire

Here are some instructions from GTR UK

or an alternative way of interrupting the signal via an insulated pin.

Those instructions only state wire colours for their converter so it's certainly not specific to stagea.  I've had one of these running in my stagea for about 10 years as a speedo corrector but I don't have the wiring handy; I will try and check in a couple of days when i do have the dash out.  But Bobby's suggested approach is the safest way; in most cases the back of the dash has printing that says what each track is (although sometimes it is in japanese as in the example he showed..)

Also, I've sent you a link to the manual

Yea i have tried the 5 wire way and still no joy. 

 

What i am trying to find out is what colour wire / what connector pinout is the ECU / Transmission signal behind the cluster and what colour wire / what connector pinout is the speedo signal.

If you can find the pin on the back of the speedo then the problem is bypassed.
