You'll need to put it in a box to prevent anything shorting. Better still is to fit a covered fuse box, which will enable you to fit a correctly rated fuse individually for each accessory you add...



Connect load feed to a terminal on one side and then link it across to all the others on that same side using 30A cable and crimp-on spade connectors. Then the terminals on the opposite side all become outputs with their own fuse.

Best type of fuse box is a distribution type, one with a single input like this one (it even has an LED indicator to show whether each output is live and if a fuse has blown!)



You connect the load from the relay to the terminal post (nut) and then you gain six outputs which each have spade terminals and their own fuse.

Good place for all things auto-electrical here
