For #1 I'd think this is outside the headlights, if you have something now you'd have it in the future. Other sensors / relays / computer decisions would be made as normal, and ultimately result in - "hey, headlights, turn on".

For #2 this would seem to be more about how you wire them. Any revised connections, jumpers, and so on.

Can't say for sure on either but maybe gives ideas?
