The computer is actually for the carburetor. The car has a Carter feedback carburetor and the TFI-IV ignition used on EFI cars. The computer system is the same as on the EFI cars (if you notice, your carb has a throttle position sensor, idle speed motor, and control solenoid on it) but instead of controlling injectors, it controls a dithering solenoid on the side of the carburetor that varies the amount of air bled into the fuel mix. My 86 Capri had the same system until I backdated the system to a 1980 Mustang-Capri 2.3L setup with Duraspark ignition and a 2 barrel Motorcraft 5200 carb. Depending on what you are planning to do with the system, I can probably help you do your conversion. Keep in mind that the 1993 head is different than the 1985 head. Also, there is no provision in the 1993 block for a fuel pump so you will need an electric low pressure (8psi) pump.
