Well my day time running lights got stuck on so I unplugged the module. Well its been unplugged for a while and just noticed that I don't have running lights any more, could this be because of the drl module? My truck is a 2002.

 

I would guess that its because you unplugged it. sorry this thread is pretty old but i need a picture of the drl module because i can't seem to find mine. the diagrams i found on google images dont help. could you take a pic of yours and post it?
