My new to me 98 Tahoe came from Florida and as such still has the American Dash Cluster. Since my trip meter isn't working and the gas gauge is fluttering I found four clusters at the wreckers with similair mileage in KMs that would fit. Is it as easy as just swapping them out? Will I affect some computer security tripy kind of thingy some where that will disable my motor? Where does the dash get it's info for Speed? Is it the VSS or does it still have a cable? Thanks
