I know this has come up on other forums before. I believe bagman1 found the p/n for it...... drop him an e-mail at mazdapart@gmail.com and he should be able to hook you up.
Update and new help
I have my driving lights installed and working but without a switch. I wired the relay to work directly off the high beams so the driving lights are on whenever the high beams are. I looked into installing a switch in the dummy panel area and it seems like a real pain in the butt area to get to so I decided not to do that. Here is what I'm thinking now and why I need more help. I would like to try to wire my new driving light relay ground to the ground from the fog light switch. My problem is that the ground for the fog light relay is also controlled from some other source including the fog light switch because the fog lights go off with the high beams even though the low beams and the fog light switch are still on. So there must be another relay in this circuit that controls the ground of the fog light relay when the high beams get turned on. Does anyone have the wiring diagram that has the fog light control and tell me if there is a second relay or does someone already know. I know this is complicated and may not be able to be done, but it would be sweet if the factory fog light switch could turn off the fog lights and my new driving lights.

While getting to those switch blanks requires a little panel removal it's not all that hard. You have to remove:
-driver's door sill (pops loose)
-driver's outer kick panel (plastic pin then pulls back)
-driver's front door weather stripping (pulls off the sheet metal)
-pop the hood release from the bottom of the panel
-remove one phillips head screw behind where the release was
-grab the whole panel and pull down and towards the back of the car.
-unplug the dimmer switch and OBDII plug from the panel
You can pop those blanks out from the front but you generally end up scratching something up, and honestly if you're running wiring it's easier to just spend the 5-10 minutes and remove the panel to give yourself room to do the wires.
The OEM fogs are set up that way because in most places it's illegal to have more than four forward facing lights on (not counting markers). There are several mods around to get the fog lights independent of the headlights though. If you don't have OEM HIDs check out THIS walkthrough. I was able to complete it in about 20-30 minutes and have mine wired to the ignition. If you do have OEM HIDs then there's another method that you can use but it requires running a wire through the firewall.
I'd personally probably run them off the OEM fogs, and wire in a switch. That way I could use the OEM switch to turn the fogs and driving lights on/off, and I could use the other switch to use just the fogs. This would be useful when having your car inspected.
I ended up getting a switch off Ebay that fit in the dummy panel. I wired that switch to the ground of the driving light relay and the power for the relay from the high beams. I left the fog lights alone. So now I can turn the fogs off or the driving lights off independantly and the fogs are only on with the low beams and the driving lights are only on with the high beams. So when I switch from low to highs the fogs go off and the driving lights come on.
