Noob question; Installing intellitronix digital gauge, (tw: LOTS OF DUMB QUESTIONS)

Ok so I am a noob-noob.

I am at that noob stage where I have the factory service manual but I am unsure on what to do with this information and apply it, much less understand it. So do those pics pertain to this?

I also have the mymopar select but damn lol

I will try and poke around the column again and see what I find that looks remotely like your pics

Ok so if I am orienting this correctly based on the notes that I found on another thread then "L" in this connector should correspond to "fuel"
