Fog light Wiring

[Alphamacaroon]

Is there a wiring diagram or instructions for the fog lights? I can't seem to find one anywhere. Maybe they are considered driving lights instead of fog lights and I'm searching for the wrong thing?

Biggest question: where are people generally pulling power for the fog lights? Are you connecting the relay switched power back to the fuse box? Directly to the battery with a fuse? Or can you tap the low-beam power line (assuming the low-beam line can handle the load, and you are okay with the fog lights only working when the headlights are on)?

Thanks in advance.
