Alpine daf9z headunit

Hi, how are you?
Currently thinking of getting the Alpine Daf9z from Japan and installing it to my Jimny. I attached the installation pdf below and a screenshot. Could anyone please help me identify the parts with blue line and the one with the yellow line is responsible for steering linked camera guide and its not mandatory right? Its on the ninth page of the pdf and other than this everything is just plug and play right?

Other than that these are the parts currently in my cart:

I know this is not what you asked, but here's a "heads up" before you buy any car audio equipment made for the Japanese market - check the frequency bands that it can receive to confirm it will be useable where ever you are.

Already checked and the Fm will work and I might buy the one available in my country. Currently I just need to identify the parts so that I could install it.
