So the little plug in the centre console with 4 prongs..

What fuse is it connected to..?

I'm wiring up the black box and there's no power to it after I sneezed and shorted it!

? is that standard?
I don't think I have one in my TJ.

If it's non standard, then it will be on a circuit common with something else, or have an inline fuse under the console / dash somewhere.

Check other devices. Does the cig lighter work? Interior light, etc? If one is out, that will help find the fuse. If nothing else is out, look hard for that in-line fuse.

It's standard..

Fuse 2 & 12 are the culprits..

The ciggy lighter was still working.. But this plug wasn't getting power.. A swapped things around etc and yeah.. Sorted!

After speaking to mcs_a8 of course..
