For those interested, I figured out how to make the Fogs stay on with the hi beams in the newer Mustangs. I looked into doing the mod that is posted over on Mustang world on my '04 Mach 1, but my Fogs worked differently. The switch is powered all the time, and there is a "foglight cutout relay" in the power distribution box. To make the Fogs stay on is quite simple. All you have to do is remove the pin that supplies the 12V to the foglight cutout relay when the hi-beams are engaged. In the pix below, the location of the relay in the power distribution box is shown (with the relay removed), and the insert shows which pin to cut. Works like a charm!! The nice thing about this mod is you can just go buy a new relay if you have inspection issues in your state.
