It is located on the left side (drivers side). It is mounted under the dash behind the hood release lever, but not mounted directly on the wall. The front of the box is mounted in a way that it is not easily recognized amongst a few wiring harnesses and electrical components. It has a black cover that is not exactly rectangular and has 1 rounded corner on the bottom left and a round nub located on top of that corner.
I suggest that you use a good light in order to see it. After you accomplish that, you will notice the fuse placement on the front cover referring you back to the owners manual, which you probably don't have because you had to use the web to locate this information, in the first place. In case you don't the fuse box diagram can be found at :
I had spend some time also trying to locate this info. This diagram is a possibly a copy of the vehicle's owners manual.
(NOTE: Inside the fuse box cover you will see that Ford has placed a Fuse Blade Puller that resembles a small plastic pair of tweezers. You will also find a set of 5 emergency fuses, which I suggest replacing immediately after you might need one in an emergency. The fuse at the top should be a 5 amp, next one down should be a 10 amp, next one on the left and down is a 15 amp, on it's right is a 20 amp then lastly, below, is a 30 amp. Only replace the fuses with its proper replacement to avoid electrical fires)
