This Receiver Wiring Harness for select 1989 to 2000 Ford, Lincoln and Mercury vehicles, allows you to install an aftermarket stereo and make connections with your car's electrical system using the factory amplifier. This harness makes installing your new stereo easier and allows you to put the factory radio back when you sell your vehicle or return it at the end of the lease. Please note your new stereo must have two pairs of preamp outputs to connect this harness.
