Where is the CAN bus located on the LEXUS RX 400h?

Hello,

I would like to intercept the CAN-Bus on the LEXUS RX 400h to monitor parameters such as engine speed, engine torque, speed, operating mode, battery status, etc.

1) Which CAN bus do I need for this? (Engine, interior, diagnostic CAN... if all of these exist) What is the speed of this bus?

2) Where can I find the connection for that? (Which CAN bus is connected to the OBD2 interface? Does the engine CAN bus have an extra connector in the engine compartment? If so, where?) However, no modifications to the vehicle are allowed, only attachments.

3) Where can I find the CAN IDs? (Are these the same for the TOYOTA Prius?) 'I actually have a few of those.'

Thank you for your help.
