http://www.yourcobalt.com/forums/interior-exterior-styling/14087-how-install-car-neon-leds-door-sensor.html

^^That's the thread I want to add some more too..

I want to do the same thing the OP is doing (When my door opens more than just my map lights will come on.) I know where the door sensor is and on post #5 Lankysean says: They are in the body of the car in the door frame near the hood of the car. Just open the doors and look, you'll see um. They don't come out so you gotta pull of the plastic molding to get at them.

What exactly is the plastic molding.. just the area around where is pushes back in?? And where do I actually ground my (-) wire? that thread doesn't show.

Thanks!

What is it you want to do exactly? Inside or out? LEDs or neons? Click on picture....

I want LEDs to come on inside the car when the door is opened... I've been trying to do some research and superbrightleds has the fuse tap for the constant power source just now I dont know where to ground so when my door opens or car is unlocked the lights will come on just like my map lights.

Pin "A10" on "C3" "Body Control Module" boxed in black in picture with single gray wire. Circled in red at "B12" twin gray wires is the dimmer supply voltage if you want them to follow cluster intensity. Otherwise Dome fuse is a good place for your fuse tap.

Any exposed metal from the vehicle unibody is ground, there is a switch in the door frame that is closed while the door is open and is opened by the door closing by depressing a button. This switch controls one setting for the dome light three way switch in the overhead. Splicing into the door frame switch will allow you to operate your LED's with the door.

Pin "A10" on "C3" goes to ground when you open a door and turns on your dome light "ON". If you supply a 12Volt to the positive side of your LEDs and wire the negative side to this pin(A10) it will come on same as your dome light and go off at same time.

Yes, dome light and map lights get their controlled ground from this pin.

Had a different idea.. I found the fuse that deals with my interior lights.. I have lights that are connected through my cigarette lighter and I plug those in manually each time I want them on. If I run power from my fuse tap to the adapter and ground to a car body bolt will my lights come on when the door is opened or unlocked? and then plug them in to my cigarette lighter when I want them to be on constantly?

NO. Dome fuse has a constant voltage unless you forget your dome light on then it will detect and shut supply voltage after 20 minutes. Again dome light is not controled by positive but rather by ground relay contact at pin"A10" of BCM "C3" connector.

Yes, the single gray wire that is "A10" dome light ground control. This will work for you.

I just ran a wire up to my dome light and spliced them together there.
Isn't that kinda taking the long road?
