good product

I purchased this as I needed it to help install a radio from my older car. The instructions were not exactly right, but the color coding helped and I was able to get it all hooked up right on the first try.

Great value

This works for the 2005 chy 300. But have to hook switch power wire to the cigarette lighter.

Save time

Save time with this adapter, need to splice wire between adapter and radio but you get more longer wire if you need to remove the radio from the dash.

This gave me a lil trouble.

I'm not much for wiring and this was a learning experience for me to no fault of the cable, but I over came and got it butted all together and the deck works great!

Electrical Connection Adapter

This adapter was perfect for my car. It was a little difficult to wire in that I had to get connectors to hook it up to my new radio, but the color coding and instructions were helpful.
