If you still have problem it is time to check debug prints with hid_listen.

Heureka and a big Thank you for your patience and assistance! I would not say that it is working, but at least something happends. There is a stream of keys coming from it, so I would probably have to debug.
And yes, my Itsy is 5v. I obviously had mixed the Data and Clock, and then I changed the + to the VCC, removed the resistor from pin 10 (the red jumper is for getting the keyboard into flash mode) and now I can almost write on it.
I don't know however if the computer shall recognize the keyboard immediately at start, that takes a little while. Anyway, I have to learn to debug now.

Update. All of a sudden everything just works smoothly, so I guess it sorted itself in some way. Now I just have to edit some keys to make it work better in Swedish.
Again, thank you for your answers!

agree. It is type-2 XT keyboard, you don't need to wire reset line.

One more question, I think I had done something with the pcb, so I bought a new one and now it is working smoothly.
But I would like to have a few more keys that I cannot find in the keymap editor, for example > and <. Is there a simple way to add these, or do I have to code or something similar?

The code you're referring is described as "Non-US \and |" in USB HID Usage Table specification, which named after symbol in UK layout. It is usually located between Left Shift and Z key on ISO keyboard layout.
https://github.com/tmk/tmk_keyboard/wiki/USB:-HID-Usage-Table See Note 9 and 10.
In TMK Keymap Editor the code is referred as "ISO \" or "Non-US Backslash" you can find in "Main" tab of "Action codes".
EDIT: In IBM XT keyboard "\" key that located between Left shift and Z is assigned to normal US backslash by default in TMK Keyboard Editor. It is due to historical reason and compatibility with later Enhanced keyboard.
