So for the past view days I've been literally sitting in my car trying to find something I could tap the "remote switch" wire from my aftermarket stereo into that I knew would not turn off until the key was pull out of the ignition. I only found two options, was the power windows or into the one of the small L.E.D. bulbs for the window and lock buttons on the driver side door. The down side to this is that once the door opens those stopped receiving power. Not exactly how the factory stereo worked before... but it was close.
