Stop ghetto rigging it!
The way a fuse works, it is designed to blow when the current flowing through it surpasses a certain level. This level is usually a little OVER whatever is deemed regular or "normal" to flow through it. Say your fogs are drawing 18 or 19 amps, (example, idk what they draw exactly), then you will have a 20 amp fuse. Just enough room for small change, but if it raises too much, due to some problem, it blows the fuse. Preventing a fire.
So a blown fuse means too much current is being drawn through it, obviously.
You either need to wire them to the headlights and upgrade the headlight fuse (i don't really recommend, but its an option), or run the fog lights separately and give them their own individual fuse like they are supposed to have.
