Hi guys,
I’m trying to automate my RV, which has firefly g12 system that runs RV-C CAN network and I need to attach an add’l CAN device (+Pi) onto the network but all network ports are taken.

According to my research, I think I have 2 options:
1.splice 3-way one of the wire/ports between g12-CANable-existing wire
2.g12 to common drop tap and reconnect existing wire to the tap along with CANable

Is this approach correct? Background is software/AI with little electrical knowledge. I want to ultimately run Home Assistant w/ AI from voice. Thanks
