This document is a page from a Mass Air conversion instruction sheet (a service procedure for converting a Ford speed-density EEC-IV engine computer system to a Mass Air Flow system). The page features a color diagram of the 60-pin EEC-IV computer connector, showing all sixty pin positions arranged in three rows (1-20 on top, 21-40 in the middle, 41-60 on the bottom) with a yellow circle marking the central connector bolt. Below the diagram are two numbered instruction steps. Step 7 instructs the reader to remove the old terminals from pins 9, 33, 52, 58 and 59 of the 60-pin connector, noting these wires can be removed because they are not used by the new Mass Air computer. Step 8 begins instructions to remove the old terminal from pin 57 and save it for step 15, then install a new red wire (the sentence is cut off at the bottom of the scan). A reader can learn which EEC connector pins must be de-populated during a Mass Air conversion and how the 60-pin connector cavities are numbered.
