Number 111 is the main 12V line that feeds the fuse panel

Number 126 is energized when the ignition is in the "cranking" position. This is the one you need for your EFI controller's cranking signal

Numbers 120 and 121 should have 12 volts with the ignition in the on position (non-cranking)- either one of them could feed your EFI's continuous 12V ignition signal, but it would probably be best to put the EFI's 12V feed off the load side of the IGN fuse.
