What is the arrangement of diagnostic LEDs?

I have been searching and the best guide to the LEDs I can find it here:
How to find and read the Diagnostic LEDs

But that one only shows 4 LEDs. This model has 5.
I did find this thread with a configuration of 5 LEDs, but it is a different configuration of LEDs. What are the 5 diagnostic LEDs?

This model has 5 LEDs but they have 4 together and 1 separate, instead of the 3 together and 2 separate of the above link. Additionally, these LEDs are arranged horizontally and not vertically. They are located towards the bottom right of the logic board, not near the power supply or fan as in other examples found. Photo attached.

I suppose it is possible there are other LEDs somewhere on the board, but none that I've noticed.

If these LEDs follow the same general idea as those previous then the biggest question is do they follow a left=1 to right=5 convention, or a right=1 to left=5 convention, or something else all together? If they do not follow the same diagnostic principals as the above linked examples, how to read these ones?

Thanks to anyone who can help!

it's left to right. It sure looks like Apple messed up in the technical manual :-)

Thank you. You've got resources I don't have access to and I appreciate it.

If I understand your "apple messed up the technical manual, but it is left to right" correctly, that second photo with 1 - 5 labelled is in the completely wrong order, but if I stick with 1 is the far left (separate) LED and then 2 - 5 are the group of 4 together, left to right, then I'll be all right?

I've got a new PSU coming in later this week and I want to make sure I can read the LEDs correctly after installing it, so this is very helpful.
