Which Blue Sea fuse block?

Just wondering who's all done this on there 4runner and which model you went with. I plan on getting one very soon to eliminate my nest of wires. I'm also debating whether or not I really need one with the negative bus. I'll probably be adding a breaker to it as well.

This is what I had in my old setup

Blue Sea 5025 ATO Fuse Block, 6-Circuit with Cover and Negative
Blue Sea 5001 SEA Mega Fuse Block
Blue Sea Mega SEA Fuses 100A-300A (5102 : 125A)
 
If you choose to run positive and ground to the accessory, the bus would be a nice place to ground small wires. If you want to run a ground to the body by whatever fixture, then it is not needed. For a boat, you can't ground to the body though.
 
I use the one with the negative and prefer it much more. Saves me from searching for a grounding location at every accessory and makes things cleaner. Mounted under the hood.

I was just looking at this one yesterday, I think I'll be buying it.

I have this one and like it a lot.
I have it mounted in my 06 and just pulled it from my 88 before I sold it to put it in my 97.

Any idea of where to mount it in the already cluttered 3rd gen engine bay?
Keep in mind I have an inline circuit breaker, and inline fuses I need space for as well.... :nerd:

Just in case it isn't clear, this fuse block is rated at 30amps per circuit but only 100amps total for the block. I'm running an inline 90AMP circuit breaker to keep from overloading the block.
It can add up really quick when I typically run a pair of fogs (100Watt each), driving lights (My 06 had 4x100W on the bumper and 4x100w on roof), rock lights (My 88 was running 6 harbor freight utility lights at 55w each), along with CB, Ham, etc.
slots get full really quick when you start wiring up lights. I was only able to run 2 lights off each circuit because the 4 on the bumper and 4 on the roof would put me over the limit to have 4 on each circuit. (100Wx4)/12=33amps

Point being is that the 12 slot is great because you never know what you will be adding in the future and the 6 at least for me wouldn't have been enough everything.

What would be the benefit of having the negative bus? I think I'd probably get a 12 circuit too. All my accessories are beginning to pile up lol.

The negative buss is helpfull because you are not always having to tap in to somewhere close to the switch or light or accessory.

It gives you somewhere that is a dedicated distribution block so that you aren't hunting around for the ground a few years down the road when you pull the circuit. I always ran a power and ground off the fuse block and have never had a problem. Only exception was the rock lights which were grounded through the housing so not need to add. I will try to add some pictures of the setup on the 4th gen. Don't think I got any from the 88.
 
In my cruiser, I have 3 blue sea fuse blocks, all of them with negatives. I preferred the negative bus so I could ensure all my devices where grounded properly, but it adds twice as much wiring.

In my cruiser I have:
6 fuse block in the engine compartment
12 fuse block under the passenger seat
6 fuse block in the rear passenger side quarter

I have a lot of accessories though and I plan on adding more so I only wanted to wire the fuse blocks once.

I also have a number of breakers to ensure there is safety in case of a short

Here is the build thread that I modeled my install after (this is not my truck or build thread)
HOW TO: POWER DISTRIBUTION Part 4- bring da power
