CD Changer (Panasonic) install in a Jetta

I've searched, and read very good instructions at http://roadsleeper.vwmafia.net but I have a question regarding connecting the adapter cable to the cable in the trunk (I have the adapter that supports the MIX function from logjam). I'm wondering if the set up is a little different for a Jetta. I can clearly see the preinstalled plug in the back, but it seems to be mounted between the wall and the preinstalled changer mount (there are two metal teeth on the mount that cover the sides of the plug). I cannot seem to get the adapter cable around these two "teeth" and cannot seem to move the preinstalled plug. I do not want to be too forceful - so can you pull the plug out from the wall a bit in order to connect the cable to the adapter?
Also, even if I can/do get the plug out of the holder, I'm not sure if the dummy plug is on or not... My adapter cable seems to fit over it but I'm not sure.
I would post this in the audio forum but people seem much more responsive in the Golf/JettaIV forum.
