This thread inspired me to do the swap too.
Here's my swap.
Original:
Dumped the 24C32F EEPROM from my original cluster and transferred mileage details (0xF54 to 0xF67) to the new one.
Original monochrome cluster's EEPROM is right on the back. Easy access.
Color LCD display's EEPROM was on the other side so complete disassembly of cluster including gauges required for access.
Done!
Pretty fun and straight forward mod!
