I have a 1996 mustang gt convetible with (4.6)?
If it includes EVERYTHING (PCM, wiring, engine assembly including intake and exhaust manifolds, etc.), it should just be a direct BOLT-IN. However, 2002 model year Mustangs do use PATS (Passive Anti-theft System), which may be an issue once everything is bolted together. Sometime in and around 1998 to 1999, Ford changed the cylinder head designs on the modular engine families to utilize "square shaped" intake ports called "Power Improved", as opposed to the "teardrop" shaped intake ports your '96 4.6L uses. This means the intake manifolds will not interchange unless an aftermarket adapter plate is used. Hope this helps.
