seems inappropriate for a device you will have on 24/7. i think mine called for 16 guage so i naturally used 14 guage.
here's another free bit of advice. put smallest fuse possible (in keeping with amp draw) on BOTH positive and negative sides.
Why use 14 gauge wire for a device drawing milliamperes. The OP could wire into the back of the cigarette socket and say put a 1amp fuse inline close to the socket ( not the device)
As to fusing both wires why???, just all fuses
close to the source of their power.
A better idea would be to wire to a dedicated breaker on the panel and use a low current
breaker. I personally don't allow inline fuses
on my boat.
