I made this schematic for anyone wanting to fix the problem with the underpowered foglight wiring on the 87-93 mustang. Hope it helps someone out. This should fix the problem and make the foglight functional even if the headlights are off.
Thanks for the link I used the same site but I like the schematic view especially because a couple things in their post seem a bit confusing and I can see how a couple peeps could get a lil frustrated when doing the fix.
