Doors open car alarm

[Kitt]

I'm trying to install an alarm but I don't know where to connect the doors opened wire from the alarm. I'm trying to do this on my 2015 Yaris (Vios) but it looks like the body ECU is very similar. Any help will be greatly appreciated:thumbup:

There are separate wires for each door:

Front Right: D33-5 (Light blue)
Front Left: D33-21 (Light blue)
Rear doors: D33-24 (orange)

D33 is the connector up high on the back side of the body ECU

Thanks for the info!!, is there any trick to connect all of them to the alarm module, without joining all of them?

You can use diodes to keep them from back feeding each other.
