Have a 96 3.8 mustang will the electronic parts of a 94 3.8 interchange? Referring to pcm+sensors etc.-

I Think they will, but 94-95 3.8 Mustangs ARE OBDII. They are one of the very few models that came with an OBDII PCM. 1996 is the primary year where nearly all models switched over to the OBDII system... aside from the Mustang. It's the 94-95 Mustang 5.0 that had the EECIV systems on them still. One of the couple of things in 94-95 3.8 that are different slightly from the 96 up, is that they have a separate ignition module, while the 96-up 3.8's use the PCM to control ignition........hope this helps
