yes, I swapped the mk5 loom for a fiesta rst one (ofac), Then once I realised the mk5 one was exactly the same except for the amal valve wiring so swapped back so I could put the ecu in the proper place.
Has he got an ofab ecu too?? sorry if thats a mong question, but the only difference I know is the map sensors are different, ofab has a weber type one.
