This document is a scanned wiring connector diagram labeled C-412, showing the ignition switch connector for a Ford vehicle (uploaded as part of a 1979 Ford Bronco wiring reference set). The diagram identifies the connector as part number 14401 and illustrates the connector body with pin/terminal locations. Each terminal is called out with its circuit number and wire color code: (2) 16 R-GR (red-green, two wires), 977 P-W (purple-white), 732 W (white), 297 BK-GR (black-green), 21 Y (yellow), 181 O (orange), a second 21 Y (yellow), and (2) 32 R-BL (red-blue, two wires). A location note states the connector is found "BEHIND I/P, L.H. SIDE" (behind the instrument panel on the left-hand side), and an asterisk key identifies the component as the ignition switch. A reader can use this page to identify the ignition switch connector's physical layout, the circuit numbers and wire colors attached to each pin, and where to find the connector in the vehicle. The document itself does not state a year, model, or engine applicability; a following connector label at the bottom edge of the scan is cut off.
