2000 Altima dome light

OK, back to the drawing board. My original plan wont work. I figured out a setup, but thats figuring the wire to the domelight was positive. But the wire I need to interrupt is negative. Now what?

Just use the purple wire from the alarm (positive trigger) and connect it the dome lightDo it right the first time

Read the entire post Raydawg. I'm trying to figure out a way to shut off the domelight as soon as I arm the alarm. As of now, it stays on for about 90 seconds after I shut the last door.

If functioning properly, the domelight supervision of your alarm should shut your domelight off as soon as you arm your alarm.  You say it's staying on after you shut the last door.  Is this with the alarm armed or disarmed?  Do it right the first time

Forget trying to rig up a way to interupt the domelight wire. Interface with the factory alarm as I previously posted and the light will function as it does from the factory. If you lock the door with the key in the drivers door cylinder the domelight shuts off immediately, correct? What I previously posted will simulate that.

JWorm, I checked into what you said. The light stays on even if you lock the door with the key. It also stays on if you lock it with the switch with the door open and then close the door. The only way I've found that the light will immediately go off is two ways, 1:by arming the factory alarm with the factory transmitter, or 2: by turning on the ignition. When you enter the car and shut the door, the light will stay on for about 60 seconds, or until you turn on the ignition, whichever comes first. Is there a wire on the factory alarm that I can interface with to duplicate this?

CutDog, I'm surprised it doesn't shut off immediately when you lock the door with the key. I think you might be best off going with the relay setup you listed in your original post. Only side effect is the domelight won't turn on if you open the door with the alarm armed....but that might be considered a good thing.

Yeah but I thought up that diagram thinking the domelight wire was positive. It's negative. How can I kill a negative wire when the alarm is armed, but ONLY for about a minute or so? I'd rather not have a relay energized the entire time that the alarm is armed. Seems like this isn't even worth the trouble! But I promised my wife I would at least try, .

somebody, anybody?
