2001 tahoe factory rearm wire

Hey Everyone, I would like to set it up when I arm my aftermarket alarm that it would rearm my factory as well. I thought it was the tan Trigger wire for the driver door, but when I have that wire hooked up and the door is open the car chimes as if the key was in, and it does no rearm. I read the the rear hatch door (pink/black) wire would rearm it. Any help would be greatly appreciated Car 2001 Tahoe Alarm Clifford RS3 (basically the same as a high end viper alarm.)

The factory alarm arms on lock when the door is open. The lock wire is light blue at the BCM in a brown plug, pin A4, positive.
