     require no additional "features" , IMO.

    When I have had a complex electrical device (often complicated by wiring 
and plugs) I have found it much easier to build a slightly larger simpler 
container and put the object to be "Water Proofed" IN this container making 
it much simpler to not only water proof it, but also a lot easier to 
determine the integrity of the seal. Secondly, a small porous bag (like 
cloth) with a bit of activated charcoal (or similar) wrapped in it for a 
desicant/chemical absorber also adds a bit of security. Remove the hard 
plastic plug(s), drill an adequate size hole, add a grommet, then insert the 
wires, reattach them to plug, then u can seal the grommet to the wires with 
clear aquarium (or similar) silicon and BAMM!! Your done!!
