Which EEC computer pins control the fuel injectors?

Pin 58 controls INJ's 1458 (bank-fire) or INJ 1 (sequential), pin 59 controls INJ's 2367 or INJ 2, pin 39 is INJ 3, and pin 35 is INJ 4.

What pin is the MAF sensor signal on?

The MAF signal is on pin 50 (second signal column).

Which pins are used for TPS and SIG-RTN?

TPS is on pin 47 and SIG-RTN (signal return) is on pin 46 in both listed columns.

What transmission signals are shown on this pin-out page?

MLPS (pin 30), OD light (pin 32), EPC (pin 38), OD switch (pin 41), TOT (pin 42 or 49), 4LOW input (pin 42), SS1 (pin 51 or 52), SS2 (pin 52), TCC (pin 53), and CSS (pin 55).

Where are the power and ground pins on this connector range?

V-PWR is on pins 37 and 57, GND on pins 40 and 60, and HEGO GND on pin 49.

This document is a continuation page (pins 29 through 60) of a Ford EEC engine computer connector pin-out table, apparently comparing pin assignments across different configurations (the column headers are on a previous page of the set). For each ECM connector pin from 29 to 60, the table lists the signal name in up to four columns. Key engine-management signals shown include HEGO and HEGO GND (oxygen sensor), NDS, CANP, EVR, TAB, TAD, SPOUT, V-PWR, GND, MAP, MAF, SIG-RTN, TPS, STI, and PIP. Fuel injector driver pins are highlighted: pin 58 covers INJ's 1458 (red) or INJ 1 (blue) and pin 59 covers INJ's 2367 (red) or INJ 2 (blue), with INJ 3 on pin 39 and INJ 4 on pin 35 in the sequential-injection column. Transmission-related columns show MLPS (pin 30), OD light (pin 32), EPC (pin 38), OD switch (pin 41), TOT (pins 42 and 49), 4LOW input (pin 42), SS1 (pins 51/52), SS2 (pin 52), TCC (pin 53), and CSS (pin 55). A reader can determine which computer pin drives each injector, sensor, or transmission solenoid, useful for speed-density to MAF conversions and diagnostics.
