the cable does not corespond to the photo, I look for the meaning of wiring taking TachoPro on the meter.

Forget cable 22, that is for 1999 model.

use the eeprom cable and circuitboard (see picture).

remove odometer, and open it.
find chip 93c66
first try without desoldering, if not work, then desolder chip.
click cable with the clip on the chip, and the other end of the cable on port 1.
go to menu: Mercedes –Sprinter-VDO-Klammer 2000
check if it reads correct old mileage, and enter new mileage.
