aux Power above the tire - What fuse / rating?

[JeepingNet]

I'm not sure all Rams have this, but above my spare tire is Aux Power that I believe is there if you are installing a topper/etc. I was trying to find out more information on it and spent the last hour searching, but I don't know what it's called and what to really look for.

1. What is the max on this circuit
2. What fuse would power this

I want to get power to my box to run a few items, and I am just trying to decide if I'll run from here (very easy) or run from the battery and fish a cable back.

There's a 3rd brake light wire, and if you have AUX switches, a BAT+ and IGN+ wire that has to be jumped inside the cab to have power.

In Cab Power FAQ -- AUX Switch power info -- Chassis power info

This is a roll-up thread that should answer most if not all questions regarding power availability in the cab. A lot of the credit for technical detail goes to @Jimmy07 without whose help and guidance much of this info would be hard to assemble. There are other contributors, you know who you...

Perfect, that got me all the info I needed! Also, it's not worth me trying to use them, so I'll just run a cable from the battery to the back. Which I tend to prefer anyway to isolate from the factory.
