Some cars have to be programmed directly by the EEPROM. Those EEPROMS can look like that:
When you can read what is written on the EEPROM, you have pin 1 on the left side on the bottom.
There are 2 different EEPROM families: the 93CX6 Series and the 24C0X Series. Depending on the series, you can the fitting adapter-board:
Warning:
