Ford Overdrive Switch Connector Pinout & Wire Colors Diagram (F-250)

This document is a wiring/connector pinout diagram for a Ford overdrive switch. It shows the switch connector face with numbered pin positions (6 and 4 at the top, 5 and 1 at the bottom) and identifies five circuits with their circuit numbers and wire color codes: circuit 57 (BK, black), circuit 298 (P/O, purple/orange), circuit 19 (LB/R, light blue/red), circuit 224 (T/W, tan/white), and circuit 911 (LG/W, light green/white). A keying dot is shown near pin 6 to indicate connector orientation. The diagram allows a reader to identify which wire attaches to which cavity of the overdrive switch connector when diagnosing electrical problems with the transmission overdrive control (such as an E4OD overdrive cancel switch circuit). No year, model, or part number information is printed on the visible portion of the scan, so applicability must be inferred from the source manual; the uploader filed it under a 1990 Ford F-250. The document is a simple, clean line drawing with clearly legible circuit numbers and wire color abbreviations.
