With the links and suggestions, I was able to get the factory radio out and the plugs installed for the Sirius Radio. (And the Sirius Radio does work!)

The one set of instructions I followed, just said to unplug the electrical connectors from the trim panel and there was no worry about reconnecting them as each one was different and they couldn't be connected wrong. The one very important bit of information they didn't bother to tell you was that each electrical connector has a lock on it to keep it in place. Trying to find these "locks" and then depress them while pulling on the connector was sure NOT a trivial process. After spending almost an hour disconnecting three plugs, I just decided to pull the trim panel out as far as it would go with the electrical connectors still attached. Luckily I had JUST enough room to sneek the radio out and add the connectors for the Sirius Radio. I guess nothing is very easy.
