Hi again Mick J,
here in Indonesia, the cars are right hand drive (similar to UK), so You don't have to think like in the mirror (a good coincidence).
I checked again, there are two vacuum lines.
1. One is white, it is still connected to something below. I will check where it from, and where it goes to next time.
2. Purple vacuum line (yes it is purple,don't know why)
it is stopped (not connected to anything)
(picture 1, see where I point to).
Hope the picture is attached successfully. Here goes
