Is it a negative trigger? Are the dome light and the door lights run on the same wire or are they separate coming from the Body Control Module? I'm looking to trigger my underbody neon via this wire. Ideal situation would be whenever I hit the key fob to unlock the doors, the neon lights would come on. After I get in and start the car, the lights would go off. If I turn on my interior dome light, I want the neon to come on too. I believe the dome light turns on via two methods. By using the overhead switch or via the trigger from BCM. I guess I might not get the dome light switch trigger to work correctly since I most likely would tap wire coming from the BCM. Anyone know where I can get easy access to this negative trigger wire?
