Good luck finding a schematic...Each year is pretty much different in wiring harness and multiplexes. My 08 isn't anything like the 06's and apparently the 09's aren't any better. I'm sure that you could simply force the multiplex to be on when the switch is on, thus giving you a pretty dash light, but I don't need another indicator light blinding me unnecessarily. I'm content with it being off.
If you've not tried it, get you some Luminetics Titanium white bulbs for low/high/fogs, and enjoy the cool DRL and Parking light look. It's wicked. My fogs are aimed higher, so I have enough light with my parking and fogs with my DRL's to ride safe at night. Maybe not legally, but it's more than enough to see. Looking at the car, it's really aggressive. Wish I had a pic.
