Hello all I have a 2015 manual mustang gt and I bought a digital dash for it. I bought the new buttons and column to go with the upgrade but when I started the car my rpm’s didn’t read and the buttons didn’t really work. I found out the gauge cluster is oem out of a 2018. Does it have to be an aftermarket gauge cluster?

 

Were you able to ever figure this out? I have run into the same issue!
