I have a 1994 f150 4x4 that had a 5.0 motor in it but
the previous owner put a 1995 5.8 out of f250 in
what computer do I need
I would say the 5.8's but it would need programming, vin and other data.
You need one for the 5.8L.
Besides the computer itself, you will need all the sensors particular to the 5.8 engine.
