Hi there - Marc and Jeffrey here (inventors of Drop Stop)! To answer your question, it appears the 2007 Ford Focus SE seat is much higher than the console so all you have to do is slide Drop Stop (through its built in slot) all the way down the seat belt and simply tuck it in. If you go to our website - http://www.BuyDropStop.com and look at picture #2 of the quad shot (the one with the iPhone), you will see a very similar set-up and this should help you to understand how it will indeed work in your car.
