Request a GMC Car Radio Stereo Wiring Diagram

Whether your an expert GMC mobile electronics installer, GMC fanatic, or a novice GMC enthusiast with an GMC, a GMC car stereo wiring diagram can save yourself a lot of time. Automotive wiring in GMC vehicles are becoming increasing more difficult to identify due to the installation of more advanced factory oem electronics.

One of the most time consuming tasks with installing an after market car stereo, car radio, satellite radio, xm radio, car speakers, tweeters, car subwoofer, crossovers, audio equalizer, car amplifier, mobile amp, car amplifier, mp3 player, ipod or any car audio electronics is identifying the correct color car audio wires for your GMC Acadia, GMC Canyon, GMC Envoy, GMC Full Size Pickup, GMC C10, GMC C20, GMC C30, GMC Jimmy, GMC S15, GMC Jimmy, GMC Safari, GMC Savanna Van, GMC Sierra C1500, GMC Sierra C2500, GMC Sierra C3500, GMC Sonoma, GMC Suburban, GMC Topkick C4500, GMC Topkick C5500, GMC Topkick C6500, GMC Topckick C7500, GMC Topkick C8500, GMC Topkick C8500T, GMC Van, GMC Yukon and GMC Yukon XL.

  • Reply ModifiedLife September 20, 2010 at 5:20 pm

    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.

    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.
