I have a 2000 Chevy Impala. I want to wire a switch, and mount it on the dash that will kill all the lights. Ideal setup: 1)Kill ALL the lights, but keeps the car running, head lights, tail lights, parking lights, indoor lights, dome light, dash board lights. That's a lot of work But that's too much work, what I really need to do is be able to kill just the headlights/parking lights. My car's headlights are manual, but have automatic override. They will turn on at night, and stay off in the day, unless I manually change that. They will automatically shut off no matter what, so the battery can never be drained by leaving the lights on. At night, however, if I manually turn off the lights, it kills the headlights, but leaves the 2 yellow parking lights on. I want a switch, that when activated, cuts the power to the head lights, and parking lights (and if I install fog lights, those too, but as of now I don't have them). Any idea's on how I would go about doing this? I could just make a cut somewhere in the light's circut, add a simple switch, then complete the circut. This would require me making cuts in 4 circuts. Since I can manually turn off the headlights, I could always just do it with 2 circuts. So either both on or both off. How would I do this with one switch? I'm thinking the one on the right would work from an enginering standpoint, but the lights don't connect directly to the battery? So how would I go about this? An I'm correct with the diagram right?
