You would not need to fuse the circuit that powers the center pin of the part # PK5231201. This only draws 1/2 an amp and does not power anything so circuit protection would not be needed. It's only function is to close the circuit to let the voltage pass through the other two pins.

You'll need to run the wires from the charger directly to your battery #HM20008. If it were my trailer, I would get a charger like this #BRW54FR because it's FREE energy!! This one is a trickle charger putting out about 7.5 watts which is…
