    I used this harness in my 2016 Transit Connect, and it worked flawlessly! The wiring is high grade, and the connectors are high quality. I used this to take my non sync Connect to a sync 3 system, which required many extras in addition to this harness, but this was the starting point. Highly recommend Naviupgrade! Best customer support I’ve ever experienced! Shipping was lightning fast!
