The best way to do that is to use a Blue Seas fuse panel, and rig it in the battery compartment. Make sure you get the panel with the negative buss on it. Run all of your accessories into it, fused appropriately for each. I would use 10 gauge wiring from the accessories into the panel and then 6 gauge from the panel, to a battery cut off switch, and then to the battery. Will make a very clean install as opposed to simply running each one to the battery which would make the post a nightmare. If your boat is rigged like mine, then you should also be able to remove the 25 amp breaker/cut off for the boats harness, and run it into the panel as well. When finished, you should have three connections at the post—charger, motor, and lead from cut off. I would call John Jones, get further advice and parts from him. When finished, it should look something like this pic. Hope this helps. (the pic is not my boat, buy I am seriously considering rigging mine like this when it comes out of winter storage)
