been lookin into that aswell and as far as i know if its got the efi loom in it then you dont need the fiesta loom. From memory you need to change the connector for the map sensor to work and have the right ecu and it should work, theres a load of stuff on this site on what u need if converting it like i did, and it says the OFAC ecu is easier to use but think it explains what u need to do to run OFAB.....

Cheers nick, im guessing it was only really needed for the mfi escorts then if the efi ones didnt come with it?!
