Okay, just looking at my manual now (guess I should've thought of that before posting!)
#19 - Automatic Headlamp System
#20 - Automatic Headlamp System
#22 - Daytime Running Lamps (DRL)
So it seams that the auto-lights have 2 separate relays... Interesting.
Then again, this is from the manual. There may only be one physical relay in my specific car (I only remember seeing one).
I just hope disabling auto-headlights is as simple as pulling the relay out without causing an annoying SVS light or some other side-effect.
