Ford Bronco Master Dash Tailgate Window Switch Wiring - C274 Connector Pinout

This document is a connector pinout diagram for the master (dash-mounted) tailgate window switch, identified as connector C274 (gray). It shows a graphical representation of the 5-pin switch connector with the wire circuits attached to each pin, including wire color codes shown both textually and with color swatches. An accompanying table lists each pin number, its circuit number and wire color, and its function: Pin 1 carries circuit 400 (Light Blue/Black), power that is hot in ACCY or RUN; Pins 2 and 5 carry circuit 57 (Black) grounds; Pin 3 carries circuit 404 (Purple/Light Green), the tailgate window switch UP signal (hot in UP); and Pin 4 carries circuit 405 (Purple/Light Blue), the tailgate window switch DOWN signal (hot in DOWN). Note that Pin 1 shows two 400 (LB/BK) wires in the connector illustration. A reader can use this diagram to identify, test, or repair the wiring at the dash tailgate window switch, for example, verifying power on pin 1 with the key in ACCY or RUN, checking grounds on pins 2 and 5, and confirming output voltage on pins 3 or 4 when the switch is operated. The document itself does not state a year, make, or model; it is watermarked "Steve83."
