Identify please

[Voodoo101]

Hi all

 

Been doing some changes on my van and found some wires that im trying to identify. They are hidden behind blanking plates. I know the Toyota use the same wiring loom for all Alphards and Vellfires, but just curious what switches would be in these places.

 

Also I have a small grill that is only on the drivers side. Anybody know what its for?

It's the mic for the Japanese handsfree

Its part of the climate control air quality monitoring system. 

You will find an airflow/temp sensor and a hose that runs back to the ac control system. 

 

The microphone is on the map light, on the right.
