  1. Hi, Im in need of a radio wiring shematic for a 2006 GMC Sierra 1500 SLE 4X4. I looked at many diagrams and none have matched up fully with the wiring in my truck. It has a thick orange wire, red wire, thin orange wire and a black/white ground wire. Then the speaker wires are all the same as the other diagrams I looked at: (yellow and brown, light blue and dark blue, light green and dark green, tan and gray), but none have the thin orange wire. Wired it up and it turns on but doesn’t produce any audio. I blew the radio fuse first attempt any speaker fuses I dont know about? Thanks for any and all help.

    I need 2001 Chevy Impala stereo wiring schematic. I’m trying to replace the front door speakers and the rear speakers. So I don’t know what wires are positive or negative.

  11. Zachary, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 1995 Pontiac Sunfire stereo or factory amplifier (if equipped) may be faulty. We suggest you take your car to an experienced audio installer and have them troubleshoot your problem. Hope this helps. Good luck with your 1995 Pontiac Sunfire radio troubleshooting.
