MIB2 Delphi JTAG pinout

So, while I was disabling CP on a MIB2 Delphi unit I used the file for the wrong version (instead of using Plus I used STD, or something like that).
While trying to find some way of interfacing and changing the data on it, I found https://turbo-quattro.com/showthread.php?31663 and understood I could probably use JTAG to interface with it and dump the eMMC, modify it and put it back on there.
I eventually found https://www.digital-eliteboard.com/t...2#post-3919110 and soldered the cables like that.
Time went on and when I had the time to try and connect it to my (very scuffed) JTAG probe (using https://github.com/phdussud/pico-dirtyJtag/) I realized I did not know what the VCC connections on the images represented. I then read further down and the person who posted it said that they had found it on the internet somewhere else.
Could someone point me in the right direction as to what I actually need to do?
For those that do not want to register I have attached the photos below.

From what I've gathered on other sources this is actually the pinout directly to the eMMC chip so I'll be able to just wire stuff up to an SD card reader and get it read/writing, finally.

Depends on what is actually the issue.
eMMc is only 1/2 of the memory that is used to boot and run those units.
Describe your issue and location and maybe there will be easier way.

Regards.
