wiring schematics for Monsoon

I gathered from your post that you have the radio but not the original vehicle, or that this was purchased from a dealer or something like that.  If this is correct, read on.  If it's not, and you do know the vehicle it came from, let us know that and I can tell you exactly what you need.  Also just to make sure I understood you correctly, the radio/cd player looks like this, right?

If you're trying to connect this to another vehicle, you need the GM reverse harness, but there are a couple different ones such as these shown here.  The plug ends go into the radio, and the bare wire ends go to the new vehicle (or to a wiring harness for that particular vehicle).
