Three connector sounds like it has coding for immo/security on the eeprom in an encoded form, which can be decoded to then be able to be written to the flash (if you need to) Single connector had coding for immo/security data on the eeprom.
I'm a little confused about how the PIN is stored and used from single connector to three connector ECU's. So the eeprom contains data that is checked against the flash, so the data in the eeprom is like a checksum for the flash data too? If you just wont to adapt keys for PSA group PIN can be calculated from eeprom - PIN can be programed to the ECU.
