I'm sorry but this cable and program will not work with the Fiesta.
To activate CC on your Fiesta you will need Ford IDS as the Fiesta setup is completely different to the Focus , Kuga and C-Max.
There area a couple of people on this forum that have completed CC to the Fiesta , speak to iNath he will guide you on what is involved, but you do need Ford IDS.
Do not attempt to use the ELM327 and ELMConfig on your Fiesta.
Thank you very much for your advice Preee (Paul).
I understand that I will not be able to use my EML327 Modification on my Fiesta 2011, I will not put at risk my ECU.
I will try to contact INath, to activate the cruise control using the Ford IDS software from my dealer.
I want to share my modification to the Bluetooth ELM327 with the forum, it may help someone.
First I made a circuit with two transistors to adapt the pins 17 and 18 of the ELM327 to RS232 TX and RX.
I use a Cisco console cable ( RJ45 to DB9). and a standard RS232 DB9 to USB adapter.
Then I also made the modification on the OBD2 pins 6 & 14 to use the standard CAN ELM or Ford DCL 6 & 11 Pins.
I used a DIP 8 switches to select various combinations.
You can see the picture and the diagram .
I hope the idea will serve somebody.

Thanks for what you do in the forum Paul.
