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?

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..

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.

I just have time to test this blue wire today. The only blue wire I can find is Blue with couple red stripe on it.   When I test this wire with Continuity test meter, with I probe on this wire and another probe to ground wire, it test beep continuity on all door closed and any door open. So I don't think this is the correct wire. I also test these same probe using voltmeter when all door closed it does not show 12v power and open 0 volt. Can you tell me how do I test this blue wire to make sure it is the correct wire for all doors open sensor trigger.

Even if it's not blue, this wire should be located in pin 5 of the connector at the interior light switch.
Touch the positive meter lead to a constant 12 volts and the negative lead to the suspected wire. Your meter should show 0 with the doors closed and 12 volts when open.
The diagram shows this wire has continuity with the ignition key cylinder light so you might check there, too.

If you locate this wire test if it shows ground with the back door open. If not you may need to diode isolate and connect to pin 6 as well.
