I changed the speedometer on an Opel agila 2005 because the speedometer was broken, now I wanted to write the original odometer reading. I have the Digiprog 3 and use the cable 29/2 do you know which pins I have to solder to make it work?
There is the software for the digiprog where you can read exactly which pins you have to use for the individual adapters:
I see you have only 3 wires, use No. 59 adapter.
