Aftermarket radio antenna adapters allow users to replace the factory radio without needing to replace the factory antenna that provides AM/FM radio
Factory radio antenna adapters are specifically for making changes to a factory setup without cutting any factory wiring.
Aftermarket radio harnesses are used specifically for installing an aftermarket radio while using the existing factory wiring and connectors.  In most cases, the wire harness plugs directly into the vehicle’s factory connector behind the radio, providing the new aftermarket radio with power and sound.
Factory radio harnesses are used in order to fix damaged factory wiring or re-install the original factory radio.
Factory backup camera, AUX & USB retention harnesses allow users to retain these factory features that are lost when replacing the factory radio with an aftermarket radio.
