Instrument Cluster change in E420

I searched this forum and found answers buried deep in the middle of other threads but they contradicted each other. I am replacing my instrument cluster in my 1997 E420. I have read that the mileage is stored in three different areas.

When I change the cluster, will the mileage on the cluster change to what is in the computers?

You can also overwrite the existing donor with a breadboard, some jumper wires, an ic chip socket, soldering iron, solder, solder wick or sucker (all easily obtainable at radio shack... cheap too) an old laptop with a serial port and internet access, and the proper software available free online. Do a search on YouTube

You mean there are some where it's legal? Where, middle of nowhere? :p

Honestly, it's just easier to just swap the eeprom instead of mucking around with eeprom programmers and whatsnot. Not everyone is computer literate, as this requires a reasonable knowledge in computer know how usage.
