Big Jib...
Welcome to iRV2!!
I don't know how the Alfa compares to our 2007 Monaco Diplomat...but the DRL relay would be over in the blank spot on the far right bank of relays in photo below. (It is in our Front Run Bay) ....I also know that it is different in a 2009 Camelot..but this just might help you!
Good Luck and Happy Camping!
