Here are the photos for my version of the fog light relay mod (yuck, I should have used heat shrink instead of electrical tape around the alligator clip, as well as a shorter wire!):
It's pretty hacky. If you run a +12v that's ignition sourced from elsewhere you can avoid cutting up the A/C relay's cover.
And here's how I did the high beam mod (fogs stay on with brights):
Locate the ground wire in the fog light connector (middle pin generally; check your FSM), cut and strip it, solder on an extension (or a quick disconnect for easy removal later; I believe all other exterior lights must turn off if brights are on in certain states for safety inspections), crimp on a ring terminal on the other end and screw it under a grounded screw. Try not to use too much length for an extension like I did, though. Very simple mod! Apologies for the crappy pictures, but they should suffice I think. Soldering the quick disconnect/ring terminals on after crimping, then electrical taping, then heatshrink will result in the most durable wire, but since this is a 3-inch ground wire you can probably get by with just crimping it on.
Hope this helps guys, if you need more info let me know.
