Hey Town,
I've got a 5 day old 08 as well, and I just disabled the DRL today. I followed the instructions in the first post, and eventually came to the connector it describes. I don't remember if the connector housing was green, but DRL was printed on the label along with something else. The two plugs going into it were color coded the same as in the first post - one white, one black. Pulled the white plug, tied it up to avoid rattling, and all has been well so far.
I drove the folks that were with me to dinner, and nothing adverse has happened. The headlights and other associated things appear to be operating as expected.
