I develop a CAN-BUS receiver (logger) with an ESP32 and CAN-BUS transceiver.

The CAN-BUS transceiver modules which I found and bought have both 120 Ohm termination resistors. But the CAN-BUS to which I want to connect this (in a modern motorcycle) is already terminated on both ends. I want to connect my device to the CAN-BUS service connector (like an OBD2 ELM327 adapter).

**Do I have to remove the resistors from these modules to make sure the bus is only terminated on both ends?**

Or do I have to keep these resistors to make sure the transceiver modules work correctly?

Is it possible that the CAN-BUS or any device on the bus will be damaged if I don't remove the resistor because the load is too high?

I bought several of those modules and I can do "try and error" if necessary.

Here are two pictures of those modules:

A little edit after a long time: I didn't upvote any answers because they are more recommendations than answers.
I used the modules like they are including the resistors and for me that worked.
But I used that in my bike for all together maybe only 10h and then I didn't do anything with this anymore. So for me and with my bike it works including resistors. But that is obviously no general answer to my question.
My answer would be now: just try ;)
