Actually - it's more than just semantics - if you did have the fog light loom, it would not be wired correctly for driving lights - for the reason that shep has pointed out - you would have to move at least move one wire.
I did this conversion on my foglight wiring a few weeks back, yes it can be done using the factory wiring, without running wires through the firewall or to the proposed driving lights, although it wasn't straight forward.
It will help if you have a wiring manual for the car to understand the "switched negative" light circuits, mine is a 2004 tho so may not be exactly the same as the 2007 that is in question.
You will need to find the high beam switched negative , I couldn't find a connector easily under the dash so I opened the loom under the dash and soldered a feed from it to my driving light switch.
There was a tricky bit with this "switched negative" setup in that the foglight's factory relay coil wiring changed state when the headlight switch was OFF / ON, the easiest fix here since there were two spare fuse positions in the engine compartment fuse box (adjacent the relay socket), was to provide a new 12v feed to the driving light relay coil so that the relay would have 12v on both sides of the coil when the headlight switch was OFF (to ensure that the driving light relay will not energise when the light switch is off).
As others have mentioned the driving lights must only operate on high beam and have a switch to disable the driving lights if necessary.
I used a supercheap illuminated switch, which with a slight trim fitted into the factory switch recess (the change of state with the fog light wiring actually helps here so that my illumination light operates when required).
If you are handy with wiring, relays and a multi-meter, and have some patience it is do-able. You will need to be able to remove a factory terminal from the relay socket, make another terminal to click into the relay socket and fuse socket, and solder and crimp the wiring for your driving light switch.
Good luck !
