High beam and fog light mod?

Does anyone have instructions to modify their foglight relay to stay on when the brights are on?

...Or if anyone has the schematic page of the highlight/foglight relay circuit, that would suffice as well.

Or confirm if the 08's and up are the same as earlier SD's.

thanks!

Might need to check state laws, some states frown on driving with fog lights on when there is no fog.

britebox.com. It requires a special unit to make happen and it is expensive. I miss the days when a couple of relays or unplugging of a wire would allow this to happen. Now it requires the unit from britebox that is 4 times what it cost for my 2004 model.

I modified my F150's fogs by lifting a relay pin and grounding it. I would think the SD's circuit is similar but I don't have schematics to confirm it
