GM Radio Harness Kit 1988-2005

This new unbranded kit provides a direct-replacement wiring harness and antenna adapter for GM vehicles built between 1988 and 2005. It covers Chevrolet, GMC, Buick, Pontiac, Cadillac, Oldsmobile and Isuzu models listed in the fitment data. The kit is designed for installers who want a plug-in solution without modifying the original vehicle wiring.

Pure Copper Conductors and Heat-Shrink Ready

Each harness uses a professional pure copper core for reliable conductivity and safe operation. The package includes one radio wire harness and one antenna adapter, both ready for heat-shrink tube connections. The design avoids cutting any OEM wiring, preserving the factory loom for future service or vehicle resale.

This harness will not work with vehicles equipped with amplified audio systems such as Bose, Infinity or OnStar. Buyers who need to retain a factory amplifier or integrated telematics module must source a different interface.
