WIRING HARNESS GM '05 COBALT '04-'05 MALIBU + MALIBU MAXX

Upgrade your GM vehicle’s audio system with the American International GWH404 Radio Wiring Harness, a plug‑and‑play adapter designed for select General Motors models from 2002 through 2012. This harness connects directly into the factory radio harness and provides a seamless way to install an aftermarket stereo without cutting into the vehicle’s original wiring.

Built with color‑coded, OEM‑style wiring, the GWH404 simplifies installation — matching power, ground, speaker, and accessory wires quickly and reliably with your new head unit’s harness. Because it plugs directly into the factory connector, you can preserve the original harness and reinstall the stock radio later if needed.
