2004 Toyota Sienna, All Doors Open Wiring?

I am installing the alarm for the Sienna 2004 van. Do any one know which wires are for all doors open/ajar on the underneath front driver side.   I know that when any doors open there is light on the dashboard show light with lcon of any doors open. Where is this wire located? I am not wanting to connect to all 5 doors on this van for detecting door opening to trigger the alarm. Any idea to do this all doors trigger wiring?mrteausa

Check the blue wire at the interior light switch.

Is the interior light switch has on/off for the all inside lights. What is the blue wire do? Negative trigger or Positive trigger? DO I need to put diode on it? I check it but only works with light switch on when off it does not work..mrteausa

This is the switch on the dash. I see it listed as negative trigger. A diode shouldn't be necessary: https://jdmfsm.info/Auto/--General--/Autoelectric%20schemas/Alarm%20cables/index2be3.html?MakeID=2&ModelID=18040 Since the white/black ground wire is only used in the on position, we can deduce the blue wire is a negative door trigger.
