A: Yes we have additional photos and various views of the product. It was just released last week so there should be new photos online shortly.
It is completely waterproof. All of the wires are sealed with approved cable sealed at the bottom of the connector and the main connector has a seal where it plugs into the mountable cap.
And yes, the relays are fused on the output circuits. The four fuses correspond to the four relays. This way all you have to do is connect the main output wires from the relays to your lights or other accessory and then connect the corresponding relay activation wires to your switches.
If you want to take the extra step of putting a main fuse or circuit breaker on the red power wire you can do that as well. We provide 6 ft. of 10 ga. wire feeding the relay pack so you should have enough wire to connect this to your buss bar or to a fuse holder and then to the battery.
