It will. You will need to use your engine harness and some of the pigtails from the 2011 harness to make it all work. Sometime in 05-06, Ford changed the pigtails on things like fuel injectors and DPFE sensors. I learned this when doing my 01 to 06 4.0 swap. You will also need to use your exhaust manifolds and factory EGR block-off's as his engine would have EGR system and your '03 doesn't.
Transmission? No clue. OP didn't list 2wd or 4x4, but he also doesn't list a transfer case. I assumed it was a 2wd donor truck. In that case, the trans would not fit your 4x4.
Bump for a good deal!!
