Mafia 3 Junction Boxes are the most important collectibles you need to find while playing the action-adventure video game developed by Hangar 13.

Their role is to help Donovan mark important items on your map such as Targets of Opportunity and all collectibles (Album Covers, Communist Propaganda, Hot Rod Magazines, Playboy Magazines, Vargas Paintings, and Repent Magazines).

Additionally, the Junction Boxes allow you to recruit Racket Bosses and to see unknown enemies in Intel View.

Mafia III includes a total of 89 Junction Boxes you need to wiretap and the following guide was created to help you locate them faster, using a series of maps, hints and a video showing all of them.

These collectibles become available the moment you complete the game’s prologue meaning that you can start looking for them as soon as you enter New Bordeaux; however, they are properly introduced while playing The Way of Flesh story mission.

During the said mission, Donovan will explain how to wiretap a Junction Box and the advantages offered by these collectibles.

How to Wiretap a Junction Box in Mafia III

In order to wiretap a Junction Box in Mafia 3 you need 3 fuses, which can be found all over the city. Without fuses you won’t be able to wiretap a Junction Box.

Since the game includes 89 Junction Boxes, it means that you will need 267 fuses to wiretap all of them.

The fuses also appear on your map after you wiretap a Junction Box and their locations are marked by green dots.

Make sure you start collecting them early in the game because you need an impressive amount to wiretap the whole city.

Assuming you have enough fuses, approach a Junction Box and you will trigger a minigame which has three steps.

For the first step, you will need to move the left thumbstick to find the spot that allows you to pry open the Junction Box. Move the thumbstick and locate the smallest green bar possible.

Now, press the X button on Xbox One or Square on PlayStation 4.

Last, hit the X button on Xbox One or Square on PlayStation 4 the moment you see the moving indicator reaching the green area.

Keep in mind that the smaller is the spot you find during the first step, the bigger will be the green area in the third step of the minigame.

Once you complete the minigame, the Junction Box is wiretapped and every Mafia 3 collectible close to it will be marked on your map along with the fuses you need to collect.

Our Mafia 3 Junction Boxes locations guide includes maps for all areas in the game. On these maps, you can see the locations of all Junction Boxes in Mafia III.

For your convenience, the tips listed below follow the same order as the one displayed on the maps, so make sure you check them out if you encounter difficulties while looking for Junction Boxes.

Last, but not least, our Mafia 3 playlist from YouTube includes a complete walkthrough for the game, along with videos for all side-missions, collectibles and achievements/trophies.
