I need a replacement engine in a 2008 that has LMM. I found low mileage LML in a wreck, which requires DEF. Can I put it into my truck using my wiring harness, computer, and etc?
The injectors are different along with the fuel pump and a handful of other parts. So swapping over the harness won't be the solution. I think the engine mounts might be slightly different. But possible to modify if I'm not mistaken
You could swap everything from your LMM over to the LML engine to make it compatible. Heads for one. That will allow you to use the same LMM injectors.
