I recently upgraded to Hella 500's which came with all the wiring to do so, but i had already modded it so i could turn on the fogs independently. I used a roll of wiring, a inline fuse holder, a relay, the factory fog switch and factory wiring.
Go from the pos on the battery, to the inline fuse
Split off to two wires coming off the inline fuse, both will be hot.
Run one to your factory switch, then from the switch to relay coil, then to ground.
The second wire coming off the fuse goes on the switch part of the relay, normally open.
Then i went from the relay to another T or split
each end of the T went to one of the fogs, then to ground!
Hope this helps
