The Metra non-OnStar interface harness helps your factory sound system transmit signals and electrical power. The part is designed for use in some GM vehicles produced between 2000 to 2005, and it allows your vehicle to play warning chimes while using the onboard speakers.
The Metra non-OnStar interface harness can be used with select year 2000, 2001, 2002, 2003, 2004, and 2005 vehicle models produced by GM. The part allows for warning chimes to be used through the onboard speakers while also transmitting signals and electrical power throughout the car.
Compatibility with Radios and Speakers
This Metra non-OnStar interface harness is not compatible with OnStar or premium aftermarket sound systems, so it's ideal for cars that don't have high-end modification options. The part hooks the warning signals, transmission feeds, and more to the speakers in GM vehicles, making it easier to hear signals than when they come from the dashboard.
Though rerouting your car's electrical wiring and signals can seem daunting, this harness can help. The harness provides a 12-volt accessory output that is easy on your vehicle's battery.
