I stumbled upon this while searching for the fog retrofit thread I found a while ago. I'll post the link here if I manage to find it, but I recall someone retrofitting the fog projectors from a GXP into the lower portion of the split fog/turns that come with other 04+ models.
That would allow you to black out the rest of the bottom half, and the GXP projectors are incredibly cheap on Rockauto. Even if they aren't amazing, I feel like they're still going to be 10x better than the ****e fog lights the rest of the 04+ GP's get.
As of now I have a jumper wire with an inline diode in my fuse box that keeps the fogs on with my lows because they're 99% aesthetic light once you have some Morimoto retrofits. Keeps them on when I use the quad high beams.
Edit: Now I see why I remembered the thread, I asked what fogs were used :P

Seems very simple.
