Scosche Audio Store

When replacing your factory radio with an after-market car stereo, the Scosche GM01B wire harness is a must for a quick and clean installation. It eliminates cutting your OE radio plug. After connecting it, your install is simple as the wires will color-match and easily connect to the after-market stereo. Without the Scosche GM01B, you would have to cut the OE radio plug and manually test each wire to connect to your after-market receiver. In addition, because you do not have to cut your OE radio plug off, the GM01B allows you to reinstall your factory receiver if necessary. A great example is if you sold your car, but wanted to keep your after-market radio and re-install your factory stereo receiver. We also recommend the Scosche BOBAZT for a quick connection that is sure to last.

Product Features:

  • Harness is used when installing an aftermarket stereo
  • Connects the aftermarket stereo harness to the vehicles factory harness
  • Designed specifically to fit the compatible vehicles
  • Plugs into the factory harness without cutting any wires
  • Standard color coded wires provide a consistent and simplified installation
  • Made from OEM quality materials
  • Compatible with Select 1978-1987 GM Vehicles

Harness Features

Premium audio systems are generally name brand systems (such as JBL, Bose, Rockford Fosgate, etc) that have been installed inside a vehicle when it leaves the factory. Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.

What I ordered was the combo radio; Bluetooth, mp3 player, usb, reader, CD player, detachable face, aux input it's fantastic too me. Even if my ear blue tooth is on and the car Bluetooth is on it will shut the radio sound down and and i talk thru my ear Bluetooth and it resumes the radio when i hang up.

Its nice to get something for nothing

July 4, 2011

When I ordered my new deck Sonic sent the install kit and the wiring kit for free, a lot of places charge you or jack up the prices and act like they're doing you a favor. I saved over $ 70.00 by buying from Sonic on just that single purchase. My wires were cut by thieves a long time ago so I just solder all my connections but if I still had the factory plug this would have made my install so much easier.

Great product

November 18, 2009

Took three times to get the right harness but that was probably because my car is a 89 Buick, not exactly a newer car. But I'd like to thank Sonic Electronics for working with me and being so easy to get in touch with and so professional with their communication, that I eventually received the right harness. Once I had the right harness, installation was a piece of cake as all wires were labeled and color coordinated. It plugged directly into the harness on my 89 Buick, which leads me to believe that if they have a harness for my car, there aren't many that they don't have. I would recommend this product to any consumer. Should also mention that harness was FREE with my purchase of head unit.

Can't get better than free

January 27, 2014

The wiring harness came free with the purchase of my new car radio, how could you hate that. Also made installing the actual radio easy as pie. (removing the factory radio was another story). Would recommend it to anyone who wants to install their own car radio

Eh...

June 14, 2011

I got this free with the radio, thank you Sonic for having free installation accessories, but I couldnt find a use for it, the 4 different 70-88 trucks I have done stereos on had already had the harness cut, and chances are with a vehicle that old most of them will have been modified, so I couldn't find somewhere to "Plug it in" had I paid for it I would have been upset, but since it was free OH well!

when using the wiring harness instructions it said to use the single yellow wire for memory but where does the connection end hook in to, I understand the wire end needs to hook up to a constant power source but don't see how?
Duane P on Mar 14, 2015
Best Answer: I did not use the yellow pigtail in my install of my 86 Pontiac, it is used when a constant 12v is not in the factory harness but a separate lead to power the head unit just check your power supply going to your adapter and find your acc and constant power leads I believe there was a yellow and red lead on it but it has been a while
