Because the Opel Agila 2005 speedometer is broken, I replaced it with a new one. The problem now is that I want to write the original odometer data to the new device. 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.
Have fun!
