Tesla Model 3 CAN-BUS Project

I have a Tesla Model 3, I've got a Raspberry Pi 0 W and connected a CAN-BUS USB module and also a 12V to 5V module, this is the parts list:

I've connected this to my Tesla Model 3 CAN-BUS using the port in the centre console between the front two seats, I have set-up the USB port so when the Raspberry Pi is connected to my home WiFi I can access the CAN-BUS directly on my iMAC as it it was connected to my car. I used SavvyCAN and Wireshark to sniff the packets and I have downloaded Model3CAN.dbc file to translate some of the information, unfortunately it doesn't translate everything.

I need help to identify the following, message ID's and packet specification for the following data:

Left / Right Indicators

Brakes

Reverse

Can anyone help?

Thank you

I have a 2022 Model Y and

I have a 2022 Model Y and often see Model 3/Y listed so maybe information here is similar. With that I noticed your linked OBDII diag port cable looks like it's only 1 CAN bus but looking at the schematic of the OVMS v3 board it has 3 CAN buses(one onboard via ESP32 and 2 offboard the ESP32). Has something shown you only need the one CAN bus for the Model 3?
