It' will be dealer fitted or later. The integrated air is the same from HQ to WB. It is the same as in the Statesman.
I bet that they have disturbed the vent when they installed it but I think you will have to have a closer look.
Both those cables are deleted with factory AC. The entire right vent is deleted and a cover plate blocks the hole.

There is a lot of confusion about the terms "factory air' & integrated air'. Also what does the term 'integrated' mean ?Originally Posted by wbute
Firstly, the unit that is being spoken about in the above posts is genuine GM-H accessory air con, which was fully integrated into the dash & was usually dealer fitted pre-sale. So it is 'factory' in the sense that it is a genuine part, supplied by GM-H & it is 'integrated' in that is built into the dash, exiting the face level vents, but it is not fitted at the factory & it is not integrated into the heater/demister to become a combined HVAC system as seen in more modern cars.
The system seen in many HQ-HZ Statesmans (BTW it wasn't standard equipment in the Deville, only the Caprice) is the factory-fitted GM unit with the big black Delco A6 compressor. These were quite expensive in the day & dealers were reluctant to order cars for stock with this unit fitted, hence the introduction by Holden of the dealer-fitted unit. So if you wanted air con in say an HZ Premier you were offered a choice of the more expensive GM Delco system & waited several weeks (or even months) for your new car to arrive or have the cheaper GM accessory kit fitted. With this second option, your new car would be ready for delivery within days & you lost the back half of your glovebox, but it was cheaper.
