That's a really good question. In my opinion, if the manufacturer is doing things correctly, the connector would just be like a splice in the red conductor. Kind of like a standard light switch is just an on-off disconnect between power and the base of a light bulb. Looking at this connector, though, that's tough to tell. A continuity tester (or to be redundant from a previous post, a multimeter) would tell if the two red wires are electrically connected inside the connector. Interesting...Tcoat, you are one of the last people on this forum I'd like to piss off and you are the first to respond to my previous post!

It may be, that if the two red conductors are not internally connected, that the other can be connected to negative. Generally speaking, a light bulb will still work if the hot/neutral or positive /negative are reversed. At any rate, the green should definitely be a ground, unless Subaru/Toyota has completely thrown convention out the window.
