I see, in yourre bms the connection is at the side.
I have a front connection.

I supose i need the CAN/RS485 connection to do this.

Any idea of the PIN layout?

Indeed i saw that already, but i can assume bottom is left pin.

Hi,

It is hard to find a connector for the 3 Pin, i als saw you can use the 4Pin micro jst.
But the label says GPS is this also just TX an RX?
Why is the connection pin for this connection RX to D4 on Uno and not TX?
