Metra 70-7903L Radio Replacement Harness - Compatible Fits for Mazda 2014-2020 (with tuner)
Install a new car radio faster with this wiring harness that plugs right into the vehicle's connectors, allowing you to connect the radio to the vehicle's electrical system. On one side, the wiring harness is color-coded, with wires you'll connect or solder to the aftermarket radio/receiver. The other side has a vehicle-specific adapter that connects directly to the original radio connectors for a quicker installation without cutting each wire.
Keep in mind that you may need additional parts to complete your installation, including a dash kit, antenna adapter, and, depending on your vehicle, a special interface adapter to retain audio controls on your steering wheel or other essential vehicle functions like navigation, video, and more. Look up your vehicle for more information.
