Personally, I would want to try to identify the switch terminals, rather than rely on a photo?
How many terminals are there on the switch?
How many key positions are there?
Are the switch terminals numbered?
If the wires (and switch) are still original, then the power from the battery feeds to the switch along the Brown/Blue wire to the number 1 switch terminal.
White is the main circuit wire from switch terminal 2 to power the ignition, brake light, charge warning light etc., so Brown/Blue to White connects across the switch (T1 to T2) with ignition "ON" which should be the second from last switch position when turning the key clockwise?
The Brown/Green lighting wire goes to switch T3, and will have a connection across the switch to the Brown/Blue at the last clockwise switch position -"Ignition and lights".
