This is stupid, but I've always wanted to keep the fog lights on when I switch to high beams. I think it looks cooler and it lights up the close and wide areas more. So yesterday I switched one wire in the fuse box and they still turn on with the headlights, but they stay on whether or not the high beams are on. Contact 3 on fuse 18 is the fog lamp relay. So I just switched the wire to a ground (I found one lonely empty tab on a grounding strip buried under wires on the bottom side of the fuse box). *POOF* It works like a charm. No modifications.
