What are the numbers on the label? Not the part number, but the catch code, and the lettering in the lower left corner. It should either be SD-EFI, MA-SEFI or SD-SEFI from what I remember. The catch code is the big letters and numbers - for example, A9L.

If it's out of a Mark VII, then it is speed density with sequential injection like a Mustang, not batch fired like a TownCar/crown Vic/Truck/T-Bird/Cougar.
Only the Mustangs and Mark VII's got the SEFI along with hyd.roller cams, but the Mark's got speed density while 88 California only and 89-up Mustangs got MAF.

thanks guys for both responses. I think this is the catch code-DX3. If this is as you say s/d but seq.fire, is it a pretty good system for an early bronco swap. I know a mass air is much better but It's hard to find a decent one in my area.
thanks ,mike

See on those labels there is the SFI-SD and the other one is SFI-MA . SFI is sequential injection; SD means speed density and MA is mass air. If it is EFI-SD, then it is not sequential injecction, but being in a Mark VII, I would think it would at least be sequential, since it is not mass air. That will tell you if it is sequential or not.
