Hey everyone. I have a 2013 fx2 supercrew with a 5.0. I just noticed my IC is off on both RPM and MPH. Even with the truck off the speedo reads just above 0 and when running the tach also reads about 300 rpm to match the speedo. Anyone have any idea what's causing this? No codes according to forscan

 

Possible someone has been in it before and didn't get them put back on in the perfect spot.

 

I've owned the truck since new. No one has ever removed the cluster.
