Question: Is every VAN wires gives the same data? about vanbus HOT 4 CLOSED

Yes, as far as I know there is only one VAN bus: the "comfort bus". There are multiple connector pins labeled "VAN data", see e.g. https://user-images.githubusercontent.com/31759302/187431278-4341194d-2f27-421e-bf0d-3705427ae11d.jpg that shows the pins also on the MFD type C display.

There are 3 different VAN buses. The odometer, radio, display, reversing radar, cd changer, A/C ECU is connected to the comfort bus which has a speed of 125 kbps. The airbag ECU and the COM2000 is on CAR1 bus and the alarm ecu is on the CAR2 bus and they have the speed of 62.5 kbps. These are 3 different buses with different purposes and with different data. Of course it doesn't matter where you connect to a specific bus, as every endpoint has access to all the data. But make sure you are on the correct bus.
Here is the topology of a Peugeot 206 (it is pretty similar to all cars with VAN bus, but higher end cars can have more nodes on the bus):

Thanks Peter! The "comfort bus" is shown red in your schematic.
