On my truck the fogs stay on with the high beams. The stock fog relay is only to turn off the fog lights when the highs are on but if you remove it and place a jumper between two of the pins, they stay on with the highs or the lows. I learned this on here and don't remember the thread. The jumper is just a piece of 12 gauge copper wire I flattened on the ends and bent into a U shape, then pressed into the two relay slots. There are 4 slots on my year relay, in the shape of a T looking at the PDC. The lower horizontal slots are the ones you jump together.
