It depends on if your first set of fogs use a relay of if they are wired to a simple toggle switch.
If using a relay, like a standard 30 amp Bosch relay, you should be able to put the second set of fogs to the output of the relay (generally terminal #30 on a Bosch relay)
You may need to upsize the wire from the battery to the Bosch relay (generally terminal #87).
If both sets include a Bosch relay, It would be best to have each set of fogs have their own relay, power wires, and independant fuse. It would be possible to wire up both seperate relays to one dash switch though if you want all fogs to come on with one switch.
If you need, I can see if I can figure out how to scan a drawing and post it on here.
