I'm looking to fix the part of the cluster where the screen lights up and tells you the mileage/lamp out and maybe other things on an 04 ram I forgot. I'm not sure I'll know how to fix that exactly so I was thinking about just swapping out with one from a junkyard or online. If I did this would there be a special procedure I need to do or just remove the old and plug in the new? Would the mileage adjust automatically? Thanks!
