The American International SH3802 Speaker Harness is a plug-in wiring adapter specifically engineered for select Chevrolet and GMC SUV and truck models from 2010 through 2021 — providing a clean, reliable way to connect aftermarket speakers to your vehicle’s factory harness without cutting or splicing wires.
