10 years ago my 2000 F350 was crushed by a tree. 4 years ago i bought a 04 F350 for a donor to put the 2000 back together.
the 2000 has 16,000 miles on it. the 2004 had 223,000 miles on it.
i used the complete cab, nose, and wiring from the 2004.
is there any way to reprogram the pcm or instrument cluster to read the engine and trans current 18,000 miles?
i have forscan, and auto enginuity.

 

I am not sure but I think it's in the speedometer that mileage is kept. The link below also infers that it is. You might check with a speedo repair company and see if they can do something like that.
