JCB hours code change

[tarts1999]

Hi,
I need help. I want to change hours code on odo(JCB4CX-4WS 2007year) . There is eeprom 8582C. Can I read it with X-Progm? I try, but not sure, that I read it correct. Now there 8500 hour, I need 8130 hour. Did the hours are in the 0x60:00 00 00 00 21 56 21 56 00 00 00 00 00 line?
Back of dash(Siemens/VDO nr 02 064 003) is plug with 10 pin. Does someone know, which pin is gnd, +30, +15 ?
Thanks!

Has it got 8534hours on it at the moment? I think 2156 need to be 1FC2 to change it to 8130hours

Thanks,
I have the same result with tachosoft, but I want to be sure, that it works. The machine is not here, so I need to know, which pin in plug is +12V. I do not have any multimeter in there(I am not in home).

8 pins connector

pin 3 = gnd / pin 4 = 12V
