  • A "lifesaver" for sure!
Style: Wire Harness Only
It's so much easier to use an adapter for an aftermarket radio installation. Too many connections and too easy to make a mistake. Just wire it to the harness for the new radio following the diagrams for the radio and the adapter. Plug the radio harness into it and the adapter into the vehicle radio harness and you are good to go. Make sure you fasten the wires securely and they are insulated from touching the vehicle or each other. I used insulated connectors and shrink tube for added protection. IMPORTANT: In my installation the vehicle harness was VERY different in the same year and radio. 1990 Chevy Suburban (I didn't expect to find an adapter to fit) I suggest you pull your old radio out and take pictures of the vehicle harness. When you find the adapter here, compare the vehicle harness to the adapter pictures to make sure you get the correct one. I didn't do that so, of course, I ordered the wrong one and had to get the correct one. (Thanks for the return policy of Amazon, EASIEST return every!) Installing a radio couldn't be easier. If I install another radio I'll definitely get the adapter harness for the vehicle. I'd also order an antenna wire extender too. A little more slack on it never hurts. ... show more

  • Perfect brand making for easy installation. Great fit and quality!
Style: Wire Harness Only
This works so well you won’t believe it. Wire up your new radio right on the table to this harness then go out to your car unbolt the old unit and install the new one faster than reading this review. Just plug it in that’s it. This company makes a quality harness adapter that fits perfectly every time. Worth every penny. Allows you to put your stock radio back in before you sell the vehicle with no hassles. Definitely recommend it! ... show more

  • Worked nicely
Style: Wire Harness Only
2002 Silverado 2500HD: Unplugged the old radio from harness, installed this harness and wired up the new radio. I was a little frustrated that ALL of the wires were labeled with (LF) which initially I mistook as Left Front speaker and started wiring and then noticed that all wires had it on them. Would have been nice if each wire were labeled correctly but not a huge deal. (Some wires were labeled with small flags or tabs) Well after looking around for a schematic, eventually I just decided to follow the color coding and it worked out exactly as it was supposed to. ... show more

Perfect for my needs. Wiring exactly matched my new radio. Plug and play with my s10 pickup. Made the whole install an easy, flawless success. Glad I bought it.

  • Does not fit
Style: Wire Harness Only
It is rather misleading to infer that this will work in replacing a factory radio with an after market one. After contacting Scosche customer service, because this adapter did not fit/work in connecting to my vehicle wire harness. I was directed to buy the GM2000SW adapter which included the chime box. This adapter was a direct plug in to my vehicle wiring harness for the radio portion of the car. After finally having the correct parts, installation was a breeze. If you are going to replace your factory radio, I suggest contacting Scosche directly and learning exactly what you need to purchase to facilitate ease of installation. Amazon is a good source to buy from, however it is somewhat erroneous in providing the correct components at times. ... show more

  • The bad, then the good news.
Style: Wire Harness Only
The first items I ordered were for my 2002 Buick Rendezvous. The bracket insert fit fine but the harness did not and caused all my gauges to malfunction. The harness instruction should have mentioned that and additional adapter was needed and it did not. In fact the adapter suggested cost almost twice what my new stereo did. Had this information been revealed I would not have purchased the faceplate adapter and radio harness for that vehicle that had steering wheel audio controls. However I took a chance and ordered a different faceplate and harness for my 1995 Chevy Silverado that DID NOT have steering wheel audio controls. Once I got all the factory wires connected to this new harness adapter everything went swimmingly and I am very happy with the simplicity and final performance of the new stereo in my truck. ... show more
