I just installed this kit in my 2010 Fusion. Everything I needed was there, even the OBD2 harness, so I didn't need to splice anything. I highly recommend printing out the instructions, that way you aren't fumbling around with your phone, because timing is important when programming the unit.
I also like the fact that this one is lock-unlock-lock to activate it, because that is the silent mode. Nice when you leave for work at 4am.
It only took me about an hour to install. This kit is a must have, especially if you don't want the extra key dongle.
