Thank you.
If it helps, i dont have a rain sensor.
I also noticed how my brown/green wire is shown in the diagram green with a very thin edge of brown.
What DOESN'T help... is that the numbers in this diagram appear to be different then the numbers printed in the plastic connector. This diagram shows "green/brown" as number 1, with black as number 4 (If I read things correctly).
So to clear some stuff up, here are 2 photo's.
