Bypass Harness for 1989–2000 Ford Vehicles

The METRA 70-5513 wiring harness lets installers bypass the factory amplifier in select Ford models produced between 1989 and 2000. It provides a direct connection between the head unit and speakers without cutting or splicing original wiring. Suitable for stereo upgrades where the OEM amplifier is removed or retained separately.

Passive Wiring Harness with No Power Draw

As a passive adapter, the harness draws no electrical power and generates no heat or audible noise during operation. It simply routes audio signals through factory-style connectors, leaving the vehicle's electrical load unchanged. Installation requires only basic hand tools and does not affect the charging system.
