Hi all,
My car is 2009 focus Mk3. It don't have auto headlight and auto wipers.

I want to do some updates for it.

Auto light control module and rain sensor were purchased for the update.

I know the rain sensor can control auto light and auto wipers, but I don't know how to connect rain sensor to my car.
Maybe connect to GEM? Or to the other module?

Who can help me? Or provide me some diagrams for this connecting?

Thank you
