 Arduino Connection:
   Vcc (pwr)         - Pin 9
   Vss (gnd)         - GND
   Chip Select (cs)  - Pin 10
   Serial Clock (sk) - Pin 7
   Data In (di)      - Pin 11
   Data Out (do)     - Pin 12
   Org Select (org)  - Pin 8

The red cable on the SOP8 clamp indicates pin 1 and should be orinted to the corner marked with a small dot on the EEPROM
