At first I thought you wanted remote on just for remote on.. I.E. sensor that power was up. Not a feed for a device. My fault for speed reading. As far as the wire well I don't know just was reading that list someone else posted.
If you just run juice back there you can use a manual toggle switch is another option. Just a pain to toggle unless you route it up front somewhere.
Otherwise you probably want to order a pro power distribution block. I have even seen them at Wally mart and Buy Moore.
