I guess what confused me is the ACC wire and the thought of one going to the factory head unit. There is no red ACC wire. The radio is not on the RAP circuit. The BCM directly controls the On/Off of the radio, and the power to the radio is supplied by an Orange B+ wire.

Not sure what the class 2 wires would do, since the aftermarket radio does not require the class 2 signals. Usually, the splicing of the class 2 is to allow the serial data to flow from the Onstar and XM modules.

But, if you fixed it...cool.
