Instrument cluster

[Courtlow]

I have a 21 ram 2500 put in a used instrument cluster out of a 22 ram 2500 having problems changing the idle hours and total hours was wondering if anybody else has had this problem and if they had any luck with changing them any help would be appreciated thank you

ON my 4th gen, I couldn't get it to change. Tried several times

On Gen 5, you can't do this with Alpha OBD. I had to ship mine out to have the idle and total hours set.
