How to connect power cables to dash mount.

This picture here is what my company provides to mount my CB in my 2021 Cascadia

My Cascadia at my old company had the same set up but I always used a cigarette lighter plug to power my CB. But that caused unwanted interference both with my CB and the radio in the truck. So my question is, how do you hook up to these posts? I'm very aware that black goes to black and red goes to red, but other than that I don't have a clue. I spent like 10 minutes one day struggling to figure this out. Maybe I'm just too dumb to figure this out. I am pretty ignorant when it comes to this kind of stuff. Google and YouTube haven't been much help either.

Any help or advice would be appreciated
