Here's what I've done for DRLs:
I hated the OEM DRLs so I turned them off with techstream(or if you added the SmartTap they turn themselves off.
I followed this video to "hack" the fog lights. I keep the fog light switch on all the time. They turn on automatically when the key is turned on and they turn off when the truck is shut off. Fog lights are now your DRLs, and you can still turn them off if you want to sneak up on people.
So i did smart tap relay for my LED and everything is working fine. Then i tried the above mod to turn my fog lights on without the low beams on and my fog lights stays on even with the engine off and keys out.
Is the smarttap causing this? I know nothing about car electrical.
Thanks
