Why did you choose an 01 donor? Nothing matches for that swap. PATS, fuel system, electrical, transmission…
Not saying it can’t be done because it has been done on here but I would consider this to be an advanced level swap. The easy 4.0 swap is to stick with a 1990-1994 donor. That is as close to plug n play as possible, you just need engine, trans, computer and wiring.
If you’re after power, a 95-97 Explorer donor with a 5.0 is the easiest performance swap.
