Metra 70-5511 1986-2000 Ford Premium Sound Radio Wire Amp Integration Harness

The Metra 70-5511 is an amplifier integration harness for Ford premium sound systems from 1986 to 2000, including the 1999-2000 Mustang. It connects an aftermarket receiver to the factory amplifier, so the OEM amp and speakers keep working after the original head unit comes out. That saves pulling door panels, running new speaker wire or replacing the amplifier just to change radios. Leads are color coded to standard aftermarket radio wiring, so power, ground, illumination and speaker connections line up without a factory wiring diagram. The 7 in leads leave slack to make connections outside the dash cavity, then tuck the bundle back in without pulling tension on a terminal. Metra builds these harnesses with flexible GXSL wire that carries full current from the radio, heat-resistant insulation for a dash that bakes all summer, and hand-assembled, pressure-fit terminals held to OEM tolerances. Installation instructions are included and the harness carries a lifetime warranty.
