    Purple = turn - will have to pick up on both side of truck behind the factory turn signal
    Brown = marker - will only have to pick up on one side of truck behind factory marker
    You find both the turn and marker in the same harness
    red = DRL this is the bulb that comes on when you put the truck into gear, should be a blue wire with a black one in the same harness behind the drl lamp
