Ford Bronco Turn Signal Switch Connector C-305 Pinout & Wire Colors (9A840)

This document is a wiring/connector pinout diagram labeled C-305 showing the mating halves of a turn signal switch connector (Ford base part number 9A840, footnoted as applicable with speed control). Two semicircular connector faces are shown side by side, one being part of the steering column assembly and the other the vehicle harness side, with each pin identified by circuit number and wire color code. The pins on both halves are: 19 BL-R (blue-red), 151 BL-BK (blue-black), 1 BL-Y (blue-yellow), 385 W-R (white-red), 283 Y-BK (yellow-black), 282 GR (green), 44 BL (blue), 810 R-BK (red-black; the column-side half shows 810 R-BK twice), 2 W-BL (white-blue), and 3 GR-W (green-white). Notes state the connector is located under the instrument panel near the steering column, that one half is part of the steering column assembly, that all connectors are gray, and that the asterisk denotes 'with speed control.' A reader can use this to identify, test, or repair the turn signal switch connector wiring by matching circuit numbers and wire colors at each pin position.
