American International Wiring Harness for 1985-2007 Ford & Select Imports - FWH594

The American International FWH594 is a plug-and-play aftermarket radio wiring harness designed for 1985–2007 Ford, Lincoln, Mercury, and select Mazda vehicles equipped with the premium (amplified) factory sound system (Ford Premium Sound, JBL, Mach AudioPhile, etc.).
This harness allows you to install a new head unit while retaining full use of the factory amplifier and all factory speakers — no need to run new speaker wire or bypass the amp. It plugs directly into the vehicle’s factory radio connectors and provides standard EIA-color-coded power/ground/speaker wires plus a blue remote turn-on lead for the factory amp.
