I just got off the phone with Karl at PAC and he explained to me that I can not read!
The instructions say to plug the PAC interface into the factory head unit. I plugged it into the bose amplifier (the plug is the same on both ends) and it does not work there. That is really too bad because it would be so much easier to plug it into the amp. Oh well!
Alls well that ends well.
