Just curious to see if anyone local has done this. I have done this mod on my last 2 cars and really liked it, but neither was a Mazda... There are 2 ways to do this that I have seen. One is done by modifying the fog light relay under the hood and running wires through the firewall to the factory fog light switch on the steering column and the other is done by modifying a few wires in the fuse box below the glove box. Here's a link to the method without running wires through the firewall.

Also, does anyone know where I can get a pinout of the plugs shown in this DIY that says exactly what the purpose of each wire is?

Damn, no one?!

ive looked into it but looked difficult for the novice i am

I used the wiring that came with my fog light kit.

Thanks! I actually did a lot of research on all the Indy Fog methods and decided against this one mainly due to the fact that the fogs are constantly on. You can add wire and run it through the firewall to the switch, but rather not run extra wires when you dont need to. In the end, I just stuck with the method utilizing the wires under the glove box.
