I contacted the company (PIE) and they wrote me back the following (below). I'm gonna order parts and give it a shot
___________
We do have parts that will work for your 97corvette. These are the part
numbers
1-Part # COR-HAR
1-Part # GM10-AUX
The COR-HAR is the cable that will allow you to use the aux because your
vehicle is not prewired. You will
be plugging it into the 3-pin and 4-pin connectors under the carpet of the
passenger seat foot panel.
And the GM10-AUX is the aux input for your audio sources which uses
RCA's in
