Ya thats what I figured.
I'm a professional installer myself & I can tell you from experience, that the newer a vehicle is the less info there is about it, wiring diagrams etc.
It takes a while before the wiring diagrams become available and accurate. The more installers in the field work on the same vehicle the better the info becomes because it has been verified & perfected multiple times over.
I figured that the installer had a hard time finding the correct wires or that the info was not available. He probably based his install on a 2004 Bonne wiring diagram or from previous experience with the older Bonnes.
I'm sure they will fix it, it should only be a couple of wires to change,
