Right, I'm talking about something else here. What I was talking about was replacing the turn signal bulbs with LED ones which have built-in drivers and use those as DRL's. Or just leave the regular stock bulbs and they can also be used as DRL's...
If you're buying a set of extra lights to use as DRL's, then just wire from the relay to wherever their input power goes.
If you're wiring your fogs to be DRL's using switched power, you'll wire a relay into 12v and switched power so that when your ignition is on, the fogs are on. Note that doing it this way means they will always be on when the key is on and you won't be able to manually turn them off without adding an extra switch to cutoff the relay trigger power.
If they're LED's and have a separate driver, then wire the relay into the driver that comes with them.
No need for a separate DRL harness in almost any case since all they really are is a pre-wired relay and it's much cheaper to just buy some wire and a relay and do it yourself.

Very useful information. Thanks!
I plan on giving this a try soon, when I get my LED hi beams I will be removing the headlights at that time.

LED Options
I've been looking at options for doing just what you say. Assuming you have incadescent lamps; I have the LED headlamps, so there's a different avenue for me BUT

These sites have options you can peruse. I've seen an LED halo that fits around the grille bar (the part that sticks out into the middle of the headlight) that you may find attractive. LINK HERE
