can you retrofit a fuel trip computer display

[dazyp]

i would like to fit a fuel trip computer to my ml270 , 2002 as it does not have this option on.
my question is if i buy a second hand computer display unit is the wiring all ready there for it and would i need any other items to get this to work ?

No ! This is due to the ECU not having the correct data therefore it will not know that you have added the trip computer !

Kindest Regards
