2009 14 ltr to a 2003 12.7 - 6ljn - 03-31-2019
Does anyone know where I can find connector jumpers for the ecm hook up going from a 2009 14 liter to a 2003 12.7? I also want to know if I need the computer out of the dash to change these two engines out?

There is place in Coos Bay Oregon that makes a harness to do what you want to do. It’s not cheap depending on truck anywhere from 2500 to 6000

this is a massively complicated swap, just FYI.
good luck
