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.

Good harness

September 15, 2014

Used this harness to install my after market Pioneer Deck. Fit perfectly to my Silverado 2000 LS1500 pick up. I tried connecting the wires with electrical tape. Dont bother, it wont hold. Use electrical nut caps on you install. Once I did that everything came together as it should. Worked out great!

You can't beat Sonic Electronix when it comes to car audio! They take great care of their customers! This wiring harness along with the dash kit was absolutely FREE with the purchase of my head unit which was purchased here! At $10 each, thats an instant savings of $20!! without having to do anything! That's the reason ill keep coming back. This kit fit perfectly and worked and looked great along with my new stereo. Came with everything needed to look like a clean, professional installation. Thanks Sonic Electronix!

will this adapt my bose speakers to another stero ?
clarence c on Jul 30, 2014
Best Answer: I'm going to say "no", because if you have Bose speakers, you most likely have a Bose amp driving them. (I never found mine, in my 2000 Camaro, but it was there and well-hidden)

You can either run all new speaker wiring from the harness to the speakers (prepare to disassemble the interior of your car) or get something like the Metra 70-1857 for Bose-equipped vehicles. I went the first route on the Camaro (two weeks), but bought that Bose adapter for a 2006 Chevy pick-up and did it in less than two hours.

Very important! Enter your exact vehicle make, model, year and trim level and search for this or another Metra Bose adapter. Metra makes myriad adapters, and choosing the wrong one could destroy that hidden amp. Also, on a Bose system, the warning-chime (keys, lights-on, seat belts) is generated by the stereo, so the adapter will be generating it instead.
