Solar Parts: Hard to find connector?

My Lance TC has had a bad connector in the solar roof wiring for some time now and it is time to do a good solid repair. I have tracked the problem to the connector through the Fridge Vent Cover. My camper is a 1996 so the first solar may have been installed a long time ago.
This connector may be out of production.

I realize there are options available such as using other types of connectors in order to eliminate the thru-vent connector, however, I would like to simply replace it with a new one. Anyone know where to find one? I guess the vernacular I am feeding Google is not being recognized.

Here are a couple of shots of the work area :::
