Following upload I also found the 110v plug male end I bought from Home Depot and attached it securely to the end of the heater pad cord. The gate valve needs a little silicone after all I think, but that's not a big deal. Basically all I'm waiting on now is the correct threaded male fitting and this habitat is ready for submersion.
