Courtesy: RP Garage If you have a ton of accessories (dashcam, gauges, footwell lights, auxiliary electronics etc) and struggle to splice into a power source or find a ground bolt every time you install something new, this mod is for you. This is a simple process that allows quickly and easily connect and disconnect accessories to their own fused power sources with no cutting or splicing required. Watch as I run through how to install a secondary accessory fuse box that runs directly from the battery but does not draw power when the car is off on my Legacy GT. You will need a fuse box, SPST relay, and some lower gauge wire depending on how much power you want to run to the box.

Note: One recommends reading the diary first and then linking to workshop notes to maintain the continuity of the theme...
On a personal level I have purchase two small fuse boxes e.g:
One for Constant Positive
This one for Ignition Positive
Leaving only the essential live connections e.g. Alarm System/ Webcam Security etc
For Accessories e.g. Radio, Lights/LEDs, Amp...etc
You may also want to include Relays in your Accessories, these act as a switch to trigger and helps with the load distribution on e.g. an exhaust cut-off motor, an LED light display, webcam USB Ports, gauges, etc...
Always good to have anything that will protect you overall wiring loom and expensive accessories
