Direct OEM replacement

The Metra 70-2001 is a 32-pin radio wire harness designed for General Motors vehicles from 1994 to 2004. It plugs directly into the factory harness at the radio location, eliminating the need to cut or splice original wiring when installing an aftermarket stereo.

Upgrades factory connector integrity

This harness replaces a brittle or missing OEM plug with high-impact ABS moulded connectors and OEM-quality terminals. The jump is worth it when the original connector is damaged, when the factory radio has been removed, or when an installer wants a secure, colour-coded interface that follows the EIA standard for plug-and-play simplicity.

Limited to power and four speakers

The interface carries only power and four speaker channels through its 32 pins. It does not transmit data, steering-wheel controls, amplification signals or any additional audio zones. Separate dash kits and antenna adapters are required to complete the installation.
