All I can say is .. if its any help .. The changers Ford use for these head units are Alpine. We get a lot of dealer upgrade requests to add these units on. The data plug on the back sometimes uses a non-standard lead to the changer. Most dealers dont want to try the ones listed in the Ford catalogues for other versions/equipment. So it's down to trial and error (and just knowing : ) )
If you get really stuck, I have the pin outs I think.
