How to Connect I2C Splitter

Hello all,

First time builder here. I have purchased a pixhawk 4 mini with the intention of connecting multiple ultrasonic sensors to create a 3d map.

My issue is embarrassingly simple. I’m not sure how to wire up the I2C Splitter to the UART & I2C port. Attached is the wire that I believe is supposed to connect the I2C Splitter and the flight controller. Which end goes into the flight controller?

Thank you very much, I could not find this info anywhere.
