Ford Bronco B&O audio amp wiring differs by model year: Pre-2025 requires our T-harness connected at the factory radio for front-to-back speaker wiring; 2025+ uses integrated rear OEM harness only.

  • Older models (pre-2025): The B&O amplifier requires running a new speaker wire T-harness from the amp (rear) to the head unit (front), connected at the factory radio, bypassing the OEM setup.
  • 2025 and newer models: The updated B&O OEM amplifier integrates fully with the existing rear wiring harness—no need to run new wires to the head unit. The original harness is retained entirely in the rear.

Trail Seven Plug & Play Amp Integration Harness for Bronco B&O (2021–2024)
Designed to pair seamlessly with the PAC ADP-FD31 A2B interface, this Trail Seven harness makes aftermarket amp installs on Bronco B&O systems truly plug and play. Pre-wired for a 4-channel amp with a mono sub amp or a single 5-channel amplifier, it also supports easy configuration for multi-channel DSP amps. Built for 2021–2024 Broncos equipped with the B&O system, this harness eliminates the need for cutting or splicing—making installation clean, fast, and reversible.
