Ford Electrochromatic Mirror Connector C911 Pinout - Wire Colors & Circuits

This document is a connector pinout reference page for connector C911 (a black, 3-pin connector, base part number 17C712) that mates to the electrochromatic (auto-dimming) inside rear-view mirror unit (base part number 17700). It includes a face-view drawing of the 3-cavity connector with cavity positions 1 and 3 labeled, plus a pinout table. Pin 1 carries circuit 295, a light blue/pink (LB/PK) wire providing voltage in Run (overload protected). Pin 2 carries circuit 57, a black (BK) wire serving as ground. Pin 3 carries circuit 140, a black/pink (BK/PK) wire that provides voltage when the vehicle is in reverse (used so the mirror stops dimming during backing). A reader can use this page to identify wire colors and circuit numbers when diagnosing or wiring an electrochromatic mirror, such as troubleshooting power, ground, or the reverse-signal input at the mirror connector. The scan was uploaded to a 2002 Ford Excursion gallery; the page itself does not state a year or model, but its format and circuit numbering are consistent with Ford wiring documentation.
