At first I was disappointed with this product. I have a 1994 Chevy Silverado K1500, which comes stock with an AM/FM stereo and cassette player. After removing the cassette player, the plug from the dash did not fit this adapter, nor did it even closely resemble it. After some research I found that you have to remove the CDM box from under the dash (near the steering column). Once this was done the new set of wires sticking out of the dash fit directly into this harness without a problem. Another perk was that the wire colors matched the factory ones for my Sony Xplod CD player.
A little splicing and it powered right up. I have no complaints about this harness or its effectiveness.

Some of the other reviews marked this harness down because it did not fit the dash wires. This is more than likely because they were trying to install the wrong set of wires from the factory stereo, instead of disconnecting the CDM box from under the dash board, then plugging into the harness.

I bought this to install a new head unit in my 1998 Saturn SC2. It arrived on time and all the wires came pre-stripped at the end which made it easy to connect to the adapter for the radio. My only issue with this was that the wires did not match up with the harness in my car when I went to plug it in, so I had to take a bunch out of the plug and put them in the right order. It was not a difficult process, and it could be achieved with a little help from a paper clip and an extra set of hands (my dad helped me out), but for some reason I was expecting them to already all be in the right order. However, this was my first time working with car electronics of any kind, so I really didn't know what to expect going in. Having said that, even with that setback it still was not difficult to use and now that everything is straightened out it works great. No major complaints. Just be prepared to adjust some wires. A quick search on youtube for removing wires from a wiring harness was all I needed to correct the problem I faced.

Made the wiring of my new aftermarket head unit in my 1997 Camaro a snap. Clear diagrams and perfect fitment.
