If it's showing an ERR on the CD player then it does sound like a wiring issue with something other than the audio wiring being tapped into. Is this that stock radio that came with the car, do you have a picture of the front and does it have a date on it? The circuit board is a bit different than I recall, the placement of the connector and the chip in the middle.
Compare to my 98:

There should only be one wire coming from the CD module, so it should be easy to track down, and although the wire colors seem to change over the years the audio signal positions have stayed the same, and yours look right based on that (the one on the right).
Here's how to probe the connector for the audio pins:
"I had a stereo connector and hooked into a 12v power supply, you may need to run it off the car's connector. I made a probe by cutting off the end from an old set of headphones, and hooking the left/right channels together, and the left/right grounds together, and then each to a paper clip, plugged it into a female/female adapter, and then into a set of speakers. You could also just cut off the end of some headphones and probe using the headphone ends, just be careful because you can get some really loud tones. Put the ground probe onto the metal case of the stereo, and then tap each pin looking for sound"

Just curious if anyone had traced down the leads heading to the amplifier IC in the radio. (or possibly pre audio processor IC) but after whatever the audio mux is? This would possibly enable not needing to have a CD PLAYING TO get AUX audio?

The reason it uses 5 wires rather then just a left/right/ground is that it's using a switching jack so it can pass either the jack audio or the CD audio through. It's switched mechanically based on if an audio cable is plugged in or not. It can be done with a regular jack, though as you note you need a CD with nothing on it since it will play both at the same time.

1998 Corvette aux input added Over the weekend I added the aux input to my radio. There was a lack of pictures for my year so when I did it I took some of the process to help anyone else who might need them. The difference is the wires you use for the left and right channels is the 4th and 5th wire not the 1st and 3rd like the newer years.
