Greetings,
Here are some things to check:
First, your factory fog lights will not work if your high beams are on (which you may not notice during the day or your high beam indicator light may be burned out). Check to make sure they are not. They MAY not work with only your DRL's on or with your headlights turned off completely, I'm not sure about that model year. Simply put, the fog lights should only work when your low beam headlights are on.
Second, check the fuse in the electrical center box under the hood or in the dash (it could be in either location). After that, it's time to change a bulb and see what happens.

Greetings,
You are correct, these are not factory fog lights. Unfortunately, since installation and wire routing is completely up to the installer, you are at the mercy of the previous owner as to where the fuse or relay for them are. If he used a relay (preferred) then it might even have two fuses - one for the main power to the lights, and one to the switch. Of course, there is no way that I'm going to be able to tell you with any degree of certainty just how these things were installed or wired. Your only hope is to spend some time under the truck following the wires from the lights to wherever they lead.
Good luck - Jonathan
