GM Antenna Adapter 1988-2008

This Metra antenna adapter connects a General Motors factory antenna to an aftermarket radio. It fits GM vehicles from 1988 through 2008 and converts the OEM connector to a mini barbed or barbless plug. The cable simplifies radio installation without cutting the original harness. It is a direct replacement part for factory antenna connections.

Installers needing factory connector retention

The adapter suits DIY installers and shops fitting aftermarket stereos in compatible GM cars or trucks where the factory antenna plug must be retained. It is not for vehicles outside the 1988-2008 model range or for radios that require a different antenna interface. Buyers needing amplified antenna support or a specific connector shape not listed should verify compatibility before purchase.
