Use this GM FM Antenna adapter cable to integrate the Delphi Delphi SA10003 FM Modulator or the Audiovox SA10112 FM Direct Adapter into any 2002 and up GM Vehicle.
2002-up GM vehicles have non-standard FM antenna plug and require this adapter to use an FM Modulator.
Plug one end of the GM's cable into your Delphi FM modulator and the other end directly into your GM factory amplified antenna with coaxial cable.
The cable is 10 inches long allowing you plenty of room to place the modulator in a convenient, hidden location.
Note: All cars require the use of the 40-GM10. The 40-GM21 connects the FM Modulator or FM Direct Adapter to your stereo, while the 40-GM10 connects the FM Modulator or FM Direct Adapter to your car antenna.
