Metra WM-GM3A GM Radio Wire Harness and Antenna Adapter

We at Metra always strive to listen to our customers. You have told us to do a better job at telling the Metra story. For over 70 years, Metra has maintained its cutting edge by paying attention to our marketplace and innovating products to fit the needs of the installer. We are the "Installer’s Choice" because we are installers. We design our products to be easy to use and easy on the eyes. If you can see a Metra product, then we haven’t done our job. Metra wires harnesses are designed with the same philosophy in mind. Their longer length for ease of installation and thicker OEM cables with OEM connectors make for a mighty install. Metra’s WM-GM3A radio wire harness is used to connect an after market radio to the OEM radio harness. Metra’s harness also includes an antenna adapter to connect the after market radio to the OEM antenna in select General Motors in 1988-2005.
