How do I permanently stop the AutoHeadlights from coming on at startup?

I want to turn my head-lights manually--NOT automatic.

Headlight switch. It's in the owner's manual.

Aside from the superb advice given above here, you can not defeat the auto turn on of the headlights.
The sensor on the passenger side dash is controlled by the BCM and it can not simply be bypassed.
The headlight switch is the only way to turn them off
