It's so you can take out the board and put it back in, without screwing up the connectors. Did you notice four are all the same 2-pin connector and can get mixed up!
I use a felt pen and put a stripe or dot (or two), or you can use masking tape etc to label the wires - CN1 (connector 1) etc. FAN, TEMP SENSOR, LEDs, PELTIER module etc.

The reason for doing this is IF you have a bunch of wires that are the same exact color or IF you have connectors have the same profile

How will you know which wire OR which connector went where

If you hook wires or connectors in the wrong place at a minimum nothing will happen or the hole board could go up in flames or blow fuse or circuit breaker

This is the reason for labeling wires or connectors and take pictures

I hope this helps you understand why I made this comment before

I do this most of the time when I work on board unless the board is marked with the wire number or jumper number and even then I will take pictures of the board any way
