Imac A1418 EMC 2889 2015. How to read the dump?

Hi all,
please help to read/write efi on EMC 2889 imac. there is no adapter on motherboard where I can connect Easy Flash Adapter. Panoma clip cant be connected also. I want to solder wires to the motherboard but I don't have its scheme and maybe someone has it or can show me where I can solder wires like on this image.
Thanks in advance.

Has anyone successfully reflashed the Winbond chip in these machines? I am very eager to see how it is done. Thanks!

I was able to read the bios on the A1418 EMC 2889 by desoldering the chip from the logic board and re-soldering it to an adapter that connects to my CH341a. It took me a long time to accept that I would have to remove the chip from the board.
