Scosche Audio Store

When replacing your factory radio with an after-market car stereo, the Scosche GM02B 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 GM02B, 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 GM02B 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.

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.

Just Works

July 9, 2014

Does everything it is supposed to do. Fitting it in my 1995 BMW 318ti was not too bad. I found a place to tuck the harness away to the left side of the head unit.

Works great with the stock wiring

September 16, 2014

Got this for my '98 BMW 328is with the HK system and stock amp. Works just as described and was a quick install. I just shortened the wires since there was a little too much between this and the head units wires. Been working great for a month now.

Easy install

December 22, 2014

The adapter made installation of my new radio a much easier task. It does make it a little more of a challenge to stuff all the wiring back into the cavity area behind the radio on a '98 bimmer. No cutting of the stock wiring is always a good thing if you can avoid it and this adapter is the trick.

Wires in the harness are loose and cause distortion on bumps

April 20, 2015

The harness fit well to my deck, but the actual wires in the harness are extremely loose, and when i go over a bump, my music cuts off for just a quick moment, i'm attributing it to the loose wires in the harness. They should be quite fixed in the harness and they're not. I would suggest the company to create a more sturdy version

Does the job, if you really need it.

January 23, 2014

If you might someday reinstall the factory unit back into your BMW then you should use this. Is your particular car so rare, is your new head unit so expensive that you might reinstall the factory unit?

This is a very large connector and is only one half of the connector. It takes up at least two square inches behind your new head unit. Valuable real estate in such a finite area of space.
Am I saying that you might be better off soldering or crimping the wires together? I am, if the first paragraph doesn't apply to your car.
I used it in my car this time and it cost me much time and effort. I will not be using it in my next install though.

Good value, but be careful

February 18, 2012

This harness is nice and it is convenient, however, if you have a stock amp in your system this harness doesnt wire it correctly. You have to connect the antenna wire on this harness to the amp wire on the cd player.

Easy to solder and distinguish the correct colours. Wires come pre-cut avoiding the hassle of de-shielding them yourself. Highly recommended.

BMW adapter

November 29, 2012

Works great! nothing like begin able to just wire the radio to the adapter and plug it right into he car! If you are doing a BMW make sure you buy he antenna adapter.

Definitely a must have piece when putting a non OEM radio in a BMW, or any other car for that matter.

Works OK but could be better

February 1, 2012

Vehicle: 2002 BMW 330i
Works OK stock but a bit bulky. I had to get key-hold saw to remove a rear plastic brace to get my new stereo (Pioeneer DEH-P5200HD) to fit. Also, if you're going to enable your steering wheel controls by adding the Axxess ASWC (which works great by the way) then you'll need to relocate the orange pin. It designated for illumination brightness control but most radios will ignore it. Instead you need to move the pin to an adjacent hole in order to pick up the steering wheel control signals (see the pinout in Axxess ASWC instruction sheet). I used pliers to yank the pin out and then put it back in the right hole.
