Next to the city stop camera. It is placed right behind the rear view mirror, the driver can't see the camera from his point of view. The passenger looks right into it, but that's just the way it is. As far as i know, this is the only place where you can put it safely.
You're absolutely right Jace1969, but you're referring to a Fiesta MK7. The TS (And I) talks about a Fiesta MK7,5. There is a huge difference between the two versions. That's why you need a software modification when you want a ESC switch in a MK7,5.
The ESC switch project is on hold right now. My dealer provided me with the wiring diagram. As far as I can tell is the wiring in place in my Fiesta. My dealer told me that the ABS pump probably needs new software. To be specific, the software from a ST. The dealer could not tell me if it would work straight away and they charge 200 pound just to put the new software in. That is a bit too much for an experiment. So if someone else has more luck, please let me know
