good evening to all, I came across a ford fiesta 1.4 68cv with ecu siemens sid 804 and I wanted to download it with the cock 1260, but I knew that I had to ground the pin 28 (if I remember correctly) of the flasheprom and I have a p? scared then, after you open the unit and locate the pin (why? the curiosity? has taken over ), I stopped for fear of any damage, any of you could kindly tell me if I can trust you to download it with this procedure??? and in the case in which damages can I run???
thank you in advance
