I have considered the "Tupper ware" housing in the past. What about heat
dissapation in that enclosed area? Is that an issue?

> Robin...If the Connector is mounted in a way that all wiring goes
DOWNWARDS from the connectors and that plastic cover, you should be OK.  I
just wanted to give advice in that I see installations all the time that
have a water path to the connector shells, which is always a bad idea.

appropriate size and then using the old "Racer's Tape - Silver duct tape to
make a final seal.
