Once again I somehow missed this thread
Anyway I have been researching this same sort of setup. I have quite a few accessories that I need a seperate fuse block to run to make it proper setup.
Here is what I have decided. I bought a 1 in 6 out and 1 in 6 out fuse block from wrangler nw to wire in, most likely above the drivers feet junction block(j/b). I want 6 switched fuses and 6 hot all the time fuses.
I don't like wiring all over the place so after an hour or so of flipping through the ewd I found that the 50A acc fuse only powers the acc relay and the three power outlets. Well the switched stuff is: Gps, xm, cb. Pretty small amp draws plus I will leave the power outlets hooked up to this fuse/relay combo. I am going to tie in in the underhood j/b.
As for the hot all the time fuses my l/c (this won't work for an lx or the newer l/c with ahc) doesn't have ahc but all of the wiring is there so I installed a 50a fuse for the ahc and again all i need to do is tap into the underhood j/b to power the hot all the time section of the fuse block.
I haven't done it yet because it will be a fairly large project rewiring all the accessories I have installed.
One side note I bought an ARB fridge (45qt about a month ago and just pulled the acc relay and bypassed it with a wire and two terminals as a temp solution until I installed all of this stuff and an additional pwr outlet in back for just the fridge. (I figure when I am done I will have 1 switched and 1 hot in back).
I also performed amperage measurements on the fridge and 2.7 amps is the max that I could get. 2.7 is on startup of the compressor, it actually drops to about 2.0 - 2.2 after it stabilizes. The pwr outlets from the factory are rated at 10A.
The wiring isn't that big, but in my opinion if you didn't want to go to the trouble of wiring another pwr outlet you don't really need to if you bypass the relay. Because we all know the japanese engineers overbuilt everything on our cars, so why would they cut corners here?? In my case it would be nice to have one more in back.
I am hoping to start on some of this tomorrow and will try to take some pics along the way for anyone that is interested.
