I want to do this mod, but still a bit confused. Can someone explain the whole grounding of the relay and such. I have no prior electrical experience so please explain this mod with the relay like teaching someone who knows absolutely nothing, haha. Thanks!
picture the relay as a drawbridge. you have power waiting at one contact and when the bridge is lowered connecting the path, it flows across the bridge out the other pin and onto the foglights.
the remaining 2 pins in the relay are like the worker operating the bridge. they tell the bridge when to go down so power can make it through to the fog lights. one pin will be the power wire you are using to activate the relay (tapped from the running lights), the other will be the ground wire which you just ground to the chassis of the vehicle anywhere.
that's just a simple story i came up with real quick off the top of my head. if you need a wiring diagram im sure i can find one for you.

You can also look at inazuma's better looking diagram here:

1) Take the dash apart so you can get to everything
2) Find the black wire going to the fog light switch and cut it.
3) Tape up the end going to the CAR
4) Connect the brown wire from the mini-relay to the black wire going TO the fog light switch
5) Ground the yellow wire and the black wire from the mini relay - there is a screw behind the dash that is very easy to use for this - but you can ground this anywhere that has chassis ground.
6) Connect the red wire to a switched +12v source. I used the center connector on the cig lighter which is also handy, but you can use any source that goes off/on with the ignition. You can even use a LittleFuse add-a-circuit to tap into the fuse box if you want.
7) Test it out and put everything back together if it works OK.
Now if the fog light switch is off, you get no fog lights in any key position.
If the fog light switch is on and the key is off, no fog lights.
If the fog light switch is on and the key in on, you have fog lights.
If you don't feel comfortable working on car electrics, I would suggest you just run by any local car installer and tell them what you want to do and provide them with these diagrams and they can fix you right up for a modest fee.
