tried the instructions above, works great.

However, I tried to install my pioneer from my previous X. I still have the harness and all and its all crimped. Behind the factory radio, there are 2 plugs one is smaller then the other. The bigger one is what plugs into the harness correct? What do you do with the small one? from what i remember from digging after the install in my original there was a small plug to that wasnt connected.

Anyway, connected what i thought was right. Powered up and all but no SOUND? was i supposed to do something with the other small plug?

Thanks
