Ford Bronco Premium Sound Radio Wiring Diagram - Amplifier & Speaker Pinout

This wiring diagram shows the radio circuit with premium sound amplifier for a Ford Bronco (uploaded as a 1996 Bronco premium radio circuit). Power feeds come from Fuse A (20A) in the engine compartment fuse box, hot at all times, on a LT GRN/PPL wire (circuit 797), and from Fuse 11 (15A) in the fuse panel, hot in ACCY or RUN, on a YEL/BLK wire (circuit 137). The radio connects through connector C211 with battery, ground (grounds G200 and G203), ignition, and illumination (LT BLU/RED, circuit 19, to the interior lights system). Speaker-level outputs pass from radio connector C282 to amplifier input connector C283, pin-for-pin with wire colors and circuit numbers (277-280, 855-859) for all four left/right front/rear channels. The premium sound amplifier (connector C212, 14 pins) receives power (797), ground (694), and a logic mode signal (689, DK BLU), and drives four speakers: left front door (ORG/LT GRN, LT BLU/WHT), left rear (PNK/LT GRN, TAN/YEL), right front door (WHT/LT GRN, DK GRN/ORG), and right rear (PNK/LT BLU, BRN/PNK), circuits 801-813. Useful for radio replacement, amplifier bypass, or speaker wiring diagnosis, since every pin, wire color, and circuit number is labeled.
