Xoutpost.com - How do I remove this panel?

I was looking for the CD changer connection (3 and 6 pin connectors) and I couldn't find any. It looks like my car was pre-wired for that and the one I was looking for was not exposed. I thought that by removing that panel I could get access to something that was hidden.
I actually pulled harder the harness last night hoping that the CD changer connector was under that and it was. So, I guess I am ok for now and I don't need to remove the panel anymore unless I need to find the 6 pin connector which I don't know if I should have it if I have DSP, do I? I found the 3 pins one. thanks guys. There is another thread for this ...
