Do they make a splitter or something for the power cable that goes into the headlights, so that I could grab that power from there and put it down on fogs that I have wired up to run at the same time as the headlights, (not individually)?

 

I'd think the extra wattage draw from the foglights would overpower the headlight fuse. Better if you used a relay from the headlight circuit to activate the foglights (would still need to send a 12v source from the battery to the fogs)

 

how would I do that?

 

The wiring kit for the fogs didn't come with a fuse box? If it did, connect it directly to the battery. I got OEM Mustang foglights, but a wiring kit from walmart which came with a switch and fuse box.

 

Also, u may want to think about splicing into the park lights instead of headlights. that way they can run independently of the headlights. Personally, it looks cooler to see a mustang with just fog lights on as the sun sets...
