Besides the EXT lamp, which was turn on for 1 second while I was driving, so I think that is a false alarm.
There is another one (above the yellow light). I asked my friend and he said that this one is alternator not giving enough charge. I only have Japanese user manual, so I have no idea the exact meaning from reading the manual.
You are correct about the tube connection, some of them are not properly or wrong connected. Now it was sorted. Also adjusted the ride height with proper ground clearance.
The fuel gauge face / grass is misty. It is not possible to see the fuel level when driving at night lol. I will need to work on that. Judging from the outlook of this gauge, it is not a VDO. Maybe it is a Smiths gauge? Any hint is welcomed.
