Hopefully their are fuses in all those wires. An easier way would be to buy a small fuse block and mount it beside the existing. Then run off of it for all your accessories or if they are all located in the cabin run a single heavier guage wire to the cabin, install the new fuse block their and run it that way. Doing the second option would clean up all the wires you have running to the current battery location. Just remember to calculate your loads and use the proper fuse.
