That is the perfect writeup! When doing the add-a-circuit, I understand that you have to find a fuse that is, in my case, on when ignition is on but off in "acc", does it matter which one? or any single fuse will work? How do I test which one I need to use?

The easiest way would be with a 12v lighted test probe (a very handy tool to have anyway) but failing that you could use a volt/multimeter, or look on-line for someone that has done this with your exact truck and mapped some of the fuse positions (like the author did for the FJC in that article).

"Once all of the under-the-hood connections have been made, you can start routing power cables from your various accessories and make the necessary connections to the fuse block. (Also, make ground connections for each individual accessory.) And, tidy everything up with cable ties as necessary."

How do you make grounds for each accesory? Is it as simple as grounding it to the fender or must they all be separate grounding points that I am unaware of?

If your accessory needs "clean" power (cb and ham radios for example) then you should run a ground wire to the fuse block. If they don't need clean power you could just ground it to the body, but it's not much harder to run a ground wire for everything back to the fuse block so that's what I do.

Hey guys, as I plan out my upgrades for my 100 series, I came across several rigs with external fuse blocks. I am pretty sure that I can add my external fuse block with some help, do you guys have writeups on adding external fuse blocks? Or maybe a link to a VERY detailed writeup, since this is the first wiring job I will do on my 100 series landcruiser. I have seen several systems with a circuit breaker located in the hood but I want to know if it is possible to put the circuit breaker in the actual truck near my oem switches so it can be shut off without having to open the hood. Im hoping my setup will allow for all the added accessories that are connected to the external fuse block will shut off when the vehicle is turned off. Thanks in advance guys!

One of my favorite type of aux fuse blocks are the ones that allow you to simply add as many fuse spots as you need. So for ex, you can order 12 fused locations that are constant hot and five that are IGN switched. Couple of vendors offer this type of fuse blocks, Wrangler NW Power products is one example.

The Blue Sea units are great units, but limited to its giant size and fixed fuse holders (can't expand). Painless wiring may offer something for you as well.

Good luck.

went with the blue sea 6 circuit fuse block instead...will update on the wiring
 
something with high current draw like an on board air compressor should probably not be run through a fuse block correct? It'd be better off wired to the battery with an in line fuse? and then chassis grounded?

Maybe. Depends on Current. The Blue Sea Safety Hub 100 (et al) will handle the high current stuff. In my setup I have 2ga welding cable from the aux battery to the fuse box. I have a separate ground terminal from the aux battery.

what plugs into the top of this thingy?

The fuse block is 7 circuits.... 3 high current on the studs and 4 lower current (up to 30A each) on a heavy duty 4pin connector... That's your thingy at the top.

I was lurking around and found these being used by HAM guys. Are these safe to run in an automotive application using Anderson powerpoles? The system seems perfect to connect all of your 12 volt equipment to a power source. They are advertised to deliver up to 40 amps total through several outlets and is available with horizontal and vertical mounts.

The Anderson Powerpole connectors look great and seem easy to use.
