Ford EEC Self-Test Diagnostic Connector Pinout - Signal Return, Fuel Pump Pins

This document is a simple pinout schematic of an EEC (Electronic Engine Control) diagnostic self-test connector, uploaded to the gallery of a 1993 Ford Taurus under the filename "eec.gif." The illustration depicts a trapezoid-shaped multi-pin connector with two pin cavities on the upper row and four pin cavities on the lower row. Three of the pins are identified by labeled callouts: "Signal Return" points to the upper-right pin, "Self Test Out" points to the second pin from the left on the bottom row, and "Fuel Pump" points to the rightmost pin on the bottom row. The other pins in the connector are not labeled. No year, model, engine applicability, part numbers, wire colors, or additional text appears in the image. A reader can use this diagram to identify which cavities on the diagnostic connector correspond to the Signal Return, Self Test Out, and Fuel Pump circuits — information commonly needed when pulling diagnostic trouble codes or testing the fuel pump circuit via the underhood self-test connector. The document belongs to an album that also includes component location and brace drawings for the same vehicle.
