Ford EEC SD to MAF Conversion Pin-Out Table Pins 55-60 - Injector, PIP, GND

Color-highlighted EEC computer pin-out reference table listing signal assignments for pins 55 through 60.

This document is a scanned fragment of an EEC computer (ECU) pin-out comparison table, covering connector pins 55 through 60. It appears to be page 3 of a 'Speed Density to MAF' (SD to MAF) conversion pin-out reference set. For each pin number, the table lists the signal assignment in two configurations (likely speed density vs. mass air flow, per the album context). Pin 55 is labeled CSS in the two right-hand columns. Pin 56 is PIP (Profile Ignition Pickup) in both left columns. Pin 57 is V-PWR (vehicle power) in both. Pin 58 differs: in one column it drives injectors 1, 4, 5, and 8 ('INJ's 1458', highlighted red), while in the other it drives only 'INJ 1' (highlighted blue), indicating a change from bank-fire to a different injector driver arrangement. Similarly, pin 59 changes from injectors 2, 3, 6, and 7 ('INJ's 2367') to 'INJ 2'. Pin 60 is GND (ground) in both. A reader can learn how the injector driver pins and other signals differ between the two EEC computer configurations when performing an SD-to-MAF swap.
