Ok, here goes.
I'd researching getting a power outlet in the rear cargo section of my 2-door JK. I do not have a sub-woofer. I would like it to run an ARB refrigerator and maybe another device by plugging it into the outlet. Something that I could switch on or off at the outlet in the rear would be great.
Does anyone out there have something like this? I'm thinking of doing it at the same time as a dual battery install.
Thanks,

This isn't exactly what you're thinking of doing, and it's in a JKU, but maybe it will give you some ideas.

Rather than have a permanent dual battery setup in the Jeep, I have a separate battery for my fridge. It provides power for the fridge when at all times, and it's wired so that it gets charged from the Jeep when the Jeep is running. The battery is in a battery box and it's strapped into a MORryde inner fender ammo can carrier.

I mounted a power outlet to the carrier and a digital volt/amp meter for monitoring battery voltage and current draw.





The fridge is on a slide next to the battery mount/power outlet.

In a late model Wrangler there is an outlet plug under the carpet in the right rear corner of the tub (passenger side rear). There are two plugs back there, a gray 8 conductor for the non-existent sub-woofer and a black 3 conductor with two wires for the aux power outlet. Whether that power plug is hot or not seems to depend on what factory options your rig was ordered with. The 20 amp fuse is M7.
This on has the wiring diagram http://www.wranglerforum.com/f40/jk-third-power-outlet-at-rear-2099921.html
This one has a nice picture of the plugs located near the RR taillights grommet.

Thank you for that. This weekend, I'll start looking.

So, it seems that the wiring will handle up to 20 amps. I guess that's not bad. I need to find a socket with a toggle on it.

And to think that I didn't want a sub woofer because I thought there was no use in it.

I wouldn't say 20 amps, maybe 10ish. It's 18ga wire for starters. Still it will run a cooler or even a fridge. Just not an air compressor or something with a heavy draw. I put a dual outlet surface mount on the plastic over the tailgate restraint bar but it was hidden when I put the top down and so it was a pain to plug stuff in. So I moved it to in front of the bar for the sport cage. https://www.amazon.com/BANDC-Marine...coding=UTF8&psc=1&refRID=HE7ZDEHCYMZTMF9ET72N

The M7 fuse can be plugged in for 'always hot' or only hot when the key is in the ACC/RUN position. However, if you want to manually switch a 'always hot' wire, then they make switches that fit the 1-1/8" opening that a marine 12v outlet uses. https://www.amazon.com/Cllena-Rocke...coding=UTF8&psc=1&refRID=PZ6MC0WFQE4K0VXPM0GH

As for the sub, it's just the wires. For a Craigs List sub to work, you would also need the factory amp. Don't know about the connectors under the dash for that - I've never looked.
