Does exactly what it was supposed to

This seems to do exactly what its supposed to (ties aftermarket deck to stock amplifier on 2003 dodge 2500 with infinity system).
Includes integration harness for steering wheel remote converter as well.
No problems with installation/etc. Simply followed instructions.

Worked to perfection

This harness worked to perfection. I have a 2006 Chrysler Pacifica - it was easy to hook up and once I did, sound! Unfortunately, I had used Sonic Electronix handy dandy guide for harnesses and purchased ones that did not work. Little did I know, 2006 Pacifica's all came with a factory amplifier, thus needed this special harness for my new dvd player. The harnesses I purchased from Sonic originally did not work - but this one does!

While it is expensive, the only other option is to rewire your entire car in order to get audio.

Works great

In case anybody is looking, like I was, to purchase and install one of these. I have a 2005 Dodge Ram 1500 with 7 speaker Infinity system with navigation and recently purchased the CHTO-02. I was skeptical after reading some of these reviews. I only used the ACC (red), constant power (yellow), ground (black), turn on (blue/white), and RCA inputs and it sounds way better than the stock deck did and no problems. Volume goes way louder, also. My Pioneer DEH-P780MP goes to 63, I think, on the volume and I've only made it up to about 55 and it was extremely loud and still no distortion. It is as loud as the factory deck at about 40-45 and this is with the 16 band EQ flat. Always had treble all of the way up on factory deck to try to get as much out of it as possible. Much better, fuller, and louder all the way around. I set the input adjustment all of the way up, as recommended by a review that I read somewhere. The date of manufacture on the unit that I purchased was 3/08 and it did have the RCA inputs.

Does what it is supposed to

Easy install and worked like it should. This is a hard to find part. Thanks Sonic

Needed for my 05 Ram with Infinity Stereo

Product worked perfectly with my truck. The deck I bought works with the factory amp and speakers.
