Hi Steve,
I see I wrote that “red & white are V+” – obviously wrong 
Red and BLACK are V+! [White is V-] I think I’ve identified the connector as a Molex “Micro-Fit” of the 3mm persuasion.
Yes, I must have something wacky on that WAN port, I’ll dig into it when I get back aboard - meanwhile the connection has been 100% to VRM since I left so I can watch my voltages & temperatures from afar
