A 2-pin connector that allows the installation of an ATM fuse in single circuit.  Great for adding accessories such as smaller rock lights and so on.  Using 14 awg wire will allow for a maximum current of up to 20 Amps; while using 12 awg will allow for a maximum current of up to 30 Amps.  It should be noted that maximum current and voltage drop are dependent on the overall length of the wire on the circuit and if the circuit is a longer a run of wire, it is possible that the awg of the wire used may need to be increased or the circuit controlled with a relay, and routed in such a way as to shorten the length of wire needed.
