This document is page 130-3 of the 1995 Ford Bronco factory wiring reference, covering the RADIO system. It shows connector face views and a pinout table for connector C257, in two variants: the standard C257 RADIO connector and the C257 RADIO JUMPER used with Premium Sound. Footnotes indicate circuit 484 (O/BK) is not used with Premium Sound (*) and circuit 689 (DB) is Premium Sound only (**). The pinout table lists all eight pins: Pin 1 – 694 (BK/LG) Ground (or 689 (DB) Ground on Premium Sound); Pin 2 – Not Used; Pin 3 – 694 (BK/LG) Ground; Pin 4 – 484 (O/BK) LCD Lighting; Pin 5 – 19 (LB/R) Instrument Panel Lamp Feed; Pin 6 – 137 (Y/BK) 12 Volt Power Feed; Pin 7 – 57 (BK) Ground; Pin 8 – 797 (LG/P) Radio Memory Power. Wire colors are given as circuit number plus color code (e.g., BK/LG = black/light green, LG/P = light green/purple). A reader can use this page to identify radio harness wires by pin, circuit number, color, and function — useful for aftermarket stereo installation or diagnosing radio power, memory, illumination, and ground circuits on a 1995 Bronco.
