Auxiliary Fuse Panels/Relay Boxes

I know there is a thread for the solid state box, but I was curious what people are running as far as an extra panel. Its undoubtedly a lot safer, cleaner and better way vs just putting a ton of wires on the battery terminals. My first new install will probably be my CB Radio which I uninstalled from the XJ today, so I figure I might as well have a good starting point for later things that'll need power like lighting, OBA, maybe on board water...

This is what I run for an aux fuse panel. I have it mounted behind the glove box and it works well. It has a relay to make 4 ports ignition controlled and the other 3 are always hot. I ended up wiring a SAE connector onto it and use that to quickly connect/disconnect things.

I guess I'll need to see where I want to mount it (inside or outside) and then go from there. On one of the links someone found cool/cheap connectors for wires. I'm already adding up things that'll need power. Then I'll need to figure out a place for switches.
Gonna do some rock lights, one set in white, one set in red (to not ruin night vision for around camp). At least those are cheap. :)

I run the sPOD system in my FJ with a low-voltage cutoff to a second battery. If I were to start over I'd look into this system called Motobrain (http://motobrain.net/). It's a very small PDU about the size of a deck of cards with eight 15 amp circuits (100 amp max) that lets you program both input and output behaviors in addition to basic wiring to switches like the sPOD. It was built with smartphone integration in mind from the start. One gripe I have is that the circuits are limited to 15 amps. The drawback in comparison to the sPOD is that the grounding and fuses aren't built in for each circuit-- the sPOD takes care of all of that for you. In the end this system may not solve the integrated aux fuse panel in a straightforward way, but it's tiny and flexible.

The Bussman system looks incredibly flexible, but requires a lot more setup and wiring work to get it working (creating jumpers, designing the circuits, etc). While somewhat expensive for what it is, I really like my sPOD because all you need to do is wire up the switches to the unit and then run wires to your devices back to the unit.

I think I'm leaning towards the Bussman setup (first link I posted in first post). Looks like a little more work to setup but it'll be nice and custom when its in and done. So I'll have to find the components and get on that.

Next question...
I am not planning on having many items that seem to need relays (as far as I know, but electronics are not my specialty). It seems like the small LED's may just be fine to be fused other than maybe the front led bar and the rock lights if there are 6-8 of them. This is what I am looking at for rock lights (and using extras for other lights if they work. http://www.amazon.com/dp/B00H7FYTRQ/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=2HK15C5CMXP2P&coliid=I7FDMR79HO2IE )

I made a list of what I can imagine my future uses will be:

CB radio
air compressor (future)
water pump (future)
Front LED bar
Right side LED
Left side LED
Awning LED
Rock LED lights
Rear LED
Truck bed LED

Any input as far as going with a relay fuse or should I just do a simple Blue Sea fuse box until I start adding stuff that needs relays?

Yea, just a simple fuse box should work, no need to get fancy. Most of your loads do not need to be fused as it's low power draw. Whatever switches you get just check the rating on them and make sure you don't go over. There's a good chance you won't need a relay for the rock lights but you would need to figure out the power consumption first.

If you end up needing any help let me know, I've done a fair bit of wiring.

Cool, guess I should've figured out what I was adding before I stayed looking ;)
I'll probably just get a blue sea or similar one then and if I need a relay I'll cross that bridge when I get there.

I just realized what I said. I would recommend fusing those loads but they don't need relays. Sorry if I confused you.

Next question.

What size wire should I use? Hoping to just get a spool of white, a spool of black and stripe my own wires instead of buying a bunch of different colors. Should 14 or 16g work? Obviously I'll need larger for the main supply and ground, but hopefully the most of everything else will work with one size.

Looks like I'd be more than good with 18 gauge for all the small stuff that wont end up needing a relay.

I’m looking for the same setup and looks like I’ll go with the sPOD.
Would like to wire up some lights to my lietner rack for setting up camp at night. However, I would like more info on a second battery setup.
