Main Harness Function
Different installations on different vehicles require different harnesses. This type is what the harness is considered. Each wiring harness we sell serves a purpose such as installing an aftermarket car stereo, integrating an aftermarket amplifier with your factory car stereo, connecting Bluetooth to your factory car stereo, and more.
Additional Harness Features
The various features that the wiring harness provides to your car stereo and/or audio system.
On-Star Compatible
This means that the harness is compatible with vehicles that have On-Star built-in.
CAN-BUS Compatible
CANBUS Ballasts ensure compatibility with ALL vehicle makes and models without the need for additional accessories. In addition, they have built-in Anti-Flickering Capacitors to help prevent lighting issues caused by voltage spikes and drops by stabilizing the power.
Compatible Premium Audio Systems
Some vehicles have higher end audio systems installed in them by the manufacturer. This specifies which premium audio systems this item is compatible with.
Vehicle Sound System
This refers to what kind of sound system the vehicle has. Premium audio systems are generally name brand systems (such as JBL, Bose, Rockford Fosgate, etc) that have been installed inside a vehicle when it leaves the factory. Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.
