Cluster problem with a 2574 international, would like to swap one from a 4900

Hey guys,

As the title says, I got my cluster on a 2574 that is always resetting when shacking the connector, looks like it's inside the cluster. I got one from a 4900 wich is visualy the same except for some buttons at the top of if (dip switch?) to set the speedo meter and axle ratio. Problem is I don't have this on mine, just 2 jumpers (see picture in link below). Is there any way to fit them?

If not, does someone know if there something easy to fix in this cluster that cause it to reset?

Thanks in advance
