I wired in an EVO-One in my 2014 Expedition Limited. I also added the EVO 9, 2-way RF kit. I really like it. I kept some of my notes if that will help. If you haven't already, buy yourself the Ford Wiring Diagrams manual for the 2011 Expedition. I found mine on Ebay for about $10. It really helped me especially for connector pinouts, locations, wire colors, etc. Unfortunately, for most of the wire connections I had to solder to the existing vehicle harnesses as Fortin does not have a quick connect harness for the 2014. I found all of the wires I needed on the driver's side kick panel and door area and then going up into the steering wheel. It was not an easy job!
