My new house has this box in the laundry room that is a hub for all the cables to the rooms. I would like to set up an outdoor antenna on the side of the house and connect it through the cable that goes inside in the second picture.

The cables in the box aren’t well labeled. I don’t know which one is coming from the outside or which one connects to the living room. I need help figuring out how best to do this. What would be the best steps for me and what tools would I need to figure this out?
