Yeah, for some reason the connector is pretty elusive. I found the PN for the side I don't need on some Italian forum, and basically the housing & terminals would cost $22. So, assuming I can get a PN for the male side, I assume it will be pricey too.
I'm thinking I'll pass on that since I can source Weatherpack/Metri-Pack connectors for a lot less. Folks will just have to do some minor cutting.
