So I put a 03 4.7 in my 05 truck and it’s not starting. I’m thinking this 03 engine is jtec I have to verify still but if it is what would it take to swap the computer systems. From my research I know I need the pcm and tcm and the harness from the engine and transmission. is there any more I would have to change cause I really don’t want to tear the engine down
