[How to Install Second Auxiliary Fuse Box in Your Car] | For Gauges, Lights, Camera | Episode 19

We quickly and easily install a second auxiliary fuse box in the car! This is a great clean option when you have a lot of auxiliary accessories wired up in your car like gauges, lights, dash cameras, horns etc

Previously I tapped all my gauges into the back of my radio behind the dash and that made things really messy and connections were not reliable. So I decided to clean up the install by installing secondary auxiliary fuse boxes where all my accessories can meet in a neat set up. The install is easy but tedious (as all electrical things are) but I am happy with the set up and installing more accessories will be much cleaner and easier (like maybe a dash cam).

*Update*
I have since making this video, added a 30A in-line fuse to the positive wires going from the fuse boxes to the positive battery terminal. It's just good practice to fuse things to prevent any chance of shortages.

*Note*
To activate the relay you will need to tap a fuse a connection from the relay switch (white) to the fuse that controls the cigarette lighter in your car. That way when your keys are on it will flip the relay switch and allow power to your auxiliary fuse boxes.
