swap from 2v 5.4 to 3v 5.4 what is needed
I have an '04 SD 4x4 with a tired 5.4 2v engine. What would it take to upgrade to a 5.4 3v ? Are the harnesses the same just a different pcm ? What about pcm compatibility with the transmission from the '04 ? looking at an '06 and and '08 complete engine with the harness included ?
thanks
