1993 Ford Taurus Data Test Connector Pinout - Self Test, Signal Return, Fuel Pump

This document is a simple pinout diagram of an automotive self-test (data test) connector, uploaded as reference material for a 1993 Ford Taurus (second generation). The image shows a trapezoid-shaped multi-pin connector with two rows of terminals: two pins on the top row and four pins on the bottom row. Three of the pins are identified with callout labels. "Signal Return" points to the second (right) pin on the top row. "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. No wire colors, pin numbers, part numbers, or year/model applicability statements are visible in the image itself. A reader can use this diagram to locate the Signal Return, Self Test Out, and Fuel Pump terminals within the diagnostic connector, which is useful when reading OBD-I diagnostic trouble codes or testing/priming the fuel pump circuit through the test connector. The file is part of an album containing related Ford Taurus wiring diagrams, connector pinouts, and test procedures, including an OBD-I code reading hookup diagram.
