I got a copy years ago from a 'dodgy' Russian website, but you can now find most of the good EDGE stuff on MACT Ford Edge's website. For downloads and documents, etc for the 2015+ models, have a look at .. Ford Edge MY2015+
Note, these are American produced manuals from Ford's online system, so they don't cover the 2.0L Diesel that we have here in the UK. For everything else, it's pretty invaluable.
