I have seen this adapter several times in the audio forum here (this is where I heard about it). You unplug the car harness on the back of the radio, plug it into this harness, then plug this harness into the radio. No wires are cut, and you end up with the speakers working, 2 RCAs, and an amp turn on wire. It is meant to add an aftermarket amp and sub. I used it with the Scion single-disc radio that is discussed a lot here, but I don't see why it wouldn't work for the stock radio as well. Everything worked great for me - steering wheel controls, speakers, sub. I decided to get all new speakers and a 4 channel amp, so I bought the 4 RCA version from the same people. I paid $56, so I was looking for $35 shipped.
If you have any questions, let me know.
