MKS gen L v1.0 (RAMPS 1.4) SDA/SCL? (1 reply)

Hi everyone,
can someone tell me, where do i find the SDA and SCL (I2C Bus) on the MKS gen L v1.0?
I need to wire three wires from an extantion board to it, SDA, SCL and a GND.

On Ramps 1.4 board easy to find.

I've read in the internet, that i can use AUX 1, D0 and D1, but i'm not sure.

Thanks for a helffull advice.

Regards,
