just remember, if its too new, it will want to see door ajar status(in the new trucks, this switch is part of the door latch), it will need a pats (passive anti theft system) tranponder key, it will also have abs and things like that intigrated into the pcm. this means that if its left out, you will have an abs light on all the time. if you dont do anything with vehicle security and it has a pats system, it will not start.
there are also alot of different modules in the newer trucks. you have the battery junction box(fuse box under the hood, gives power to many different modules), the sjb (smart junction box, gives power mainly for body functions and systems), pcm, rcm (restraints control module), the insturment cluster is also its own module in the newer trucks. they all work together, and if one isnt working right, none of them will.
Not tring to discourage you, but as someone who works on these every day, this is going to be VERY labor intensive, especially if you want to do it right and have every module working like its supposed to.
However, if you go with a V10 out of say, a 99-01 f250, i believe that the pcm is the only module that has anything to do with the engine.
