16-Pin Radio Wiring Harness

The Metra 70-1771 is a 16-pin radio wiring harness adapter specifically designed for select 1998-up Ford, Lincoln, and Mercury vehicles. This harness provides a crucial interface for installing an aftermarket stereo system while completely preserving the original factory wiring. Its plug-and-play design ensures a direct connection to the vehicle's existing radio connector, eliminating the need for any cutting or splicing of factory wires. The harness is engineered to manage all essential connections, including power (12V constant, 12V accessory, and ground), illumination, and the positive and negative leads for all four speakers. This comprehensive coverage ensures that your new head unit receives the necessary power and signal distribution. Constructed with high-impact ABS OEM plastic molded connectors, the Metra 70-1771 guarantees a secure and precise fit within the vehicle's dashboard. The leads are color-coded according to standard aftermarket wiring conventions, simplifying the process of matching them to your new receiver's harness for a quick and efficient installation. This approach also ensures the installation is fully reversible, should you need to return the vehicle to its stock configuration. Specific wire functions include yellow for 12V constant, red for 12V accessory, black for ground, and orange for illumination. Speaker wiring is color-coded for front left (white/white-black), front right (gray/gray-black), rear left (green/green-black), and rear right (purple/purple-black). The product page mentions compatibility with specific car models such as Mustang, Probe, Ranger, Taurus, Tempo, and Thunderbird.
