This is page 6 of 9 from Ford Motorsport Performance Equipment's installation instructions (document IS-M-9000-T51*, dated 1/21/93) for the F-Series Mass Air conversion kit. The page covers removal of the factory EEC-IV processor (engine computer). Figure 9 illustrates the 60-pin harness location in the engine compartment near the brake reservoir. A note explains that the removal procedure differs by year: 1987-1991 trucks require removing the EEC processor through the inner kick panel area, while 1992 trucks require removal through the engine compartment. The page then details the 1987-1991 EEC-IV removal procedure in Steps 20-25: locating the driver's side scuff plate near the floor of the door opening, removing the scuff plate retaining screws, removing plastic push pins to take off the driver's side kick panel (shown in Figure 10 with insulator and push pin locations), removing the processor insulator, removing the EEC-IV processor bracket/bolt, and finally removing the production EEC-IV processor. This page is part of a multi-page mass air flow (MAF) conversion procedure applicable to Ford F-Series trucks and related vehicles like the Bronco.
