  1. Cowboy, we are happy we could help you with your 1992 Pontiac Grand Prix stereo wiring diagram needs.

  2. Todd, you can use the radio switched 12V+ wire to run your antenna. The only problem with using the switched power wire is that your antenna will always be extended even when your not listening to the radio. If you don’t mind this, the radio switched power wire is the way to go. Hope this helps. Good luck.

  3. What can I do about the antenea trigger wire (Pink) when installing stereo in 1992 Pontiac Grand Prix. The stereo I am installing does not have this option. Can I jump the antena somehow?
