I got a good deal on a 1994-95 5.0 and T5 out of a Mustang from a private party. I did not get an ECU. When I called Automotive Electronic Solutions the guy wanted to know which ECU I wanted? He had about 5 different ones. He thought a F4ZF-EA might be the right one? Is this the one I need? On Car-Parts.com they break them down as Cobra or Non-Cobra. Any advice would be helpful.
