American International Wiring Harness for 2003-2013 Ford/Mercury/Hyundai - FWH692

The American International FWH692 is a plug-and-play amplified-system wiring harness designed for 2003–2013 Ford, Lincoln, Mercury, and select Hyundai vehicles equipped with a factory premium/amplified sound system (Ford “Audiophile”, “Mach 1000”, “Shaker 500/1000”, or factory subwoofer systems). This harness allows you to install an aftermarket head unit while keeping the factory amplifier and all factory speakers (including door subs) fully operational — no bypassing the amp or running new wires. It plugs directly into the vehicle’s factory radio connectors and provides standard EIA-color-coded power/ground wires plus the critical blue remote turn-on lead that activates the factory amplifier.
