Accessory Fuse Block and Cable Install in a 4WD

How to add a secondary fuse block to your vehicle to power accessories. I install a fuse block in my Land Rover Defender to power additional accessories and lights. I explain what you will need ...

Slide the accessory's connector pin into the car fuse box. If there is no connector pin, unscrew the fuse box connector screw with a screwdriver. Strip 1/2 inch of sheathing from the wire with a wire crimper tool. Slide the bare wire under the connector and tighten the screw.

This thread will show how I wire up a 6 fuse auxiliary fuse block, relays, 6 rocker switches, and eventually 6 accessories (lights, water pump, extra 12v sockets etc.). I will try and keep this up to date as I actually build, wire, add accessories etc. Also, please note I have no idea what I am doing.

In this video we show you how to tap into your fuse box. You may need to do this ta day a radar, Sirius XM, or an amp turn on. the fuse taps we us e you can get here

Install the fuse as close to the battery (or “hot” end) as possible. This way if the fuse operates, there will be less wire that can still carry power. Fuse all circuits that can have power running through them. A circuit is the full (+) to component to (-) loop. No fuse is needed on the (-) return wire for this type of system.

high guys im hoping to wire in my aux fusebox onto my defender this weekend. i have a fuse box which is capable of 100amp per bank. there are 2 banks. my question is if i was to run a 170amp cable from my battery to my relay then to the 170amp mega fuse then from there carry the cable on . then j...

Use a high quality fuse box with positive and negative busbars. Unlike in a car, where circuits can be grounded at virtually any point, circuits on a boat should start and end at the fuse box to prevent stray electrical currents. Use stranded copper wire (tinned copper is best) with an insulation that can withstand the marine environment.

Installing an auxiliary fuse block keeps your aftermarket electrical system tidy, provides dedicated power, and takes a lot of the hair-pulling out of the wiring process. No more jamming wires into the factory fuse block, or cluttering up your battery posts.

A fuse box is a precursor to the modern breaker panel. It frequently is rated for only 60 amps, and it has far fewer fuses than modern breaker panels have breakers. It's easier and safer to add 220-volt wiring to a breaker panel than it is to add it to a fuse box, which is a job for an electrician.

Notice the fuse shown – this needs to be circuit protected with an inline fuse like this one. I’m also showing the negative return wiring for the bilge pump in this step. A stereo memory line might be another “bypassed” load
