As a totally anal
modification, which I make with a lot of low voltage electrical items aboard, is the addition of easily removable connections such as:
My thinking is if it broke once, it will again. While, perhaps, not the best
type of connection, I apply liberal amounts of corrosion protection and tend not to use them in very damp locations.
One advantage with using these IMO is one can polarize the feed wires by alternating male and female ends so whatever device will only reconnect in one way.
