yo Cat,
Stop at the Ford Dealer and ask for the Vehicle Emission Control Information(VECI), Vacuum Diagram & Calibration Parts List for 88 & UP with your VIN
It will show;
PROCESSOR AND CALIBRATOR ASSY., (EEC-IV) with the Ford Part Number; hopefully we can use it to find the Calibration number (posted on driver B pillar door jamb in later years such as 92-96.
With the number, yards that use Hollander Interchange data base can located the correct unit for you.
If the Dealer won't give you the VECI w/Parts List; let me know, because a Ford Tech Rep @ Ford told me the dealers do have them; Ford used to have them on-line for free, but shut the site down last year.
To get accurate info when posting Qs, soon in your profile, include your year, Model (XLT, etc.) engine size; transmission (AOD or manual transmission...), transfer case (manual lever operated or Push Button type), locking hub types (automatic or manual dial) and any major mods such as body or suspension lift.

easiest way to ID a EFI302 from EFI351 is to inspect the EGR system. They use different exhaust tubes to connect the EGR to the exhaust. The 302 gets exhaust from the lower intake, while the 351 gets exhaust from the passenger exhaust manifold. Much quicker and easier than measuring the lower intake.
