The 94 Cobra computer is not compatible with the 86-88 computer connector. You would need most of the 94 car's wiring harness and more electrical work to make it mate up with the chassis wiring harness of the car you currently have.
The car listed in your profile shows up as a 93 model which already has mass air. The 94 computer is still not pin compatible with a 93 model car.
There is no info about your car's model year or mods, which make it hard to tell what's in your car.
That's why it is a good idea to use the sig under the user control panel (User CP) option. It allows you to post your car year & mods, which help greatly when troubleshooting things. No, it is not there for us to snoop and see any "Secrets" you have hidden away under the hood. Be a good stangnetter and update your sig for future reference & don't keep us guessing.
