If your GM vehicle needs an AXGM-Series radio replacement interface, an extension harness might also be necessary, depending on the vehicle setup. Many GM models locate the factory tuner remotely, such as in the rear of the vehicle or behind the passenger-side kick panel, which requires extra harness length for proper installation. The AXEXH-GMLN31 extension harness offers the additional reach needed to connect your AXGM-Series interface at the radio location to the factory tuner.
Features:
Extension harness for select GM AX-Series interfaces
Cloth-tape wrapped for an OE look and added protection
48” length
