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.

I have a 2000 toyota camry v6. It has 6 speakers (2 tweeters, 2 front, 2 rear) but this harness seems to have connections for only 4 speakers as stated in the description. Will this mean my twwters will be silent?
Koushik K on Jul 26, 2015
Best Answer: Correct. The harness has connections to 4 speakers; the tweeters are actually connected to the front door speakers, so there is no need for extra two cables, I changed both front speakers and tweeters, no need to worry, just splice the new tweeters into the existing cables

Will this work on a 2002 sr5 4runner? Don't want to buy without being 100% sure.
A shopper on Oct 26, 2015
Best Answer: I put mine in a 2001 Tundra. While I initially panicked because the colors of the wires coming out of the truck did not match the wiring harness, I found a chart of Toyota wiring online which shows that it will work fine. Once I got all the wires crimped together, it just snapped into place and works great.

Will this fit in a 2002 toyota avalon xl?
A shopper on Feb 23, 2015
Best Answer: Hello,

Assuming the NON-AMPLIFIED System, Yes. If your vehicle has the amplified system, then you seek the Metra 70-8113. (Please check the back of your Aftermarket Headunit. If it DOES NOT have FOUR RCA Preouts, then instead pick up the Scosche TA03B) .

will this work on a 1989 Toyota Supra? and is it compatible for any stereo?
A shopper on Oct 8, 2014
Best Answer: Hello,

Yes, this is the harness for a Standard Audio '89 Supra. Although Universal, the harness is Vehicle Specific, not headunit specific, so please check the stereo for matching connections.
