Radio Wiring Harness

What is a Radio Wiring Harness?

Radio wiring harnesses are used to connect a car's stereo or infotainment unit to your factory wiring harness in the case that your vehicl'es original harness has been damaged, ensuring optimal radio performance in your vehicle's new stereo. A radio wiring harness is a complete set of wires, terminals, and connectors used to connect radio components from your original stereo to the new unt. Without a radio harness, it is common to have to cut wires and hard wire the radio connector into the factory harness during radio installation. With a radio wiring harness, connector adapters keep you from having to cut wires to install a new radio. In the case of reinstalling a factory radio, these connectors allow for plug-and-play installation. Some radio wiring harness options also include adapter plugs for steering wheel controls and other factory radio options.
