In looking at other pictures, it appears that I may have the wrong adaptor. Mine doesn't have the square yellow plug that is shown in other pictures of the harness.
In looking at the Bergvill site, it looks like I have the "ISO audio/power harness Porsche 968/928 CR-1".
The first picture is the harness that I do have, the second picture is of what I
should have.
Ugh, I wonder how long it will take to get the correct harness from Norway. Ironically, I just got back from Norway!
