2000 Chevy c/k truck domelight supervisio

Which is the correct wire on the vehicle for the domelight supervision? Where is it located? At the domelight one wire has constant 12v. and the other doesn't show ground or 12v. The door pin has three wires. One is ground all the time, one has ground when the door is open but doesn't turn on the domelight and the third shows ground when door is open but 12v when closed. If I put ground pulse to that wire when the door is closed, the dome light comes on. Will it hurt to use that wire? Any info would be appreciated.

the third shows ground when door is open but 12v when closed. that is the wire you want to use....you have a neg door trigger......you would wire up a relay as follows: pin 87 ground pin 86 neg coming from alarm(should be a - disarm output) pin 30 will go to the domelight wire pin 85 fused 10 amp 12 voltsGood Luck
