I would suggest making a couple changes to your idea. Unless you have a separate switch that you are going to install to control the lights you don't want to use the "hot in run" wiring because then the lights will be on all the time the truck is running including the day time and this is not only not needed but will wear them out sooner. You want to be able to control them. I always like using existing wiring and switches so I would just take them onto the fog light system.
Basically the way this works is your lights should have a power wire and control wire. You hook the power wires to the battery, and the control wire to the wire I point to in the diagrams. This way when you turn the fog lights on, these lights will come on but they get power directly from the battery.
Unfortunately I don't see any "aux" fuse cavities that you can use for this. Unfortunately OEM's didn't provide this type of options as they built it for what they wanted and that is it. In recent years, I know Ram has done this for larger trucks like 3500 -5500 trucks.
If this doesn't make sense, send me a picture of the connectors you have on these lights and if they provided a wiring diagram, then I can help figure out what wire goes where.
Also, let me know if you are going to use your own switch mounted in the cab. If you are then we can pretty much just run them off a main fuse unless they came with their own circuit protection.
