Thanks for making me aware of this thread! The pictures are great for what I'm doing.That's great Chris! We have a member that's looking to get the low beam functioning with the H7 lamp for a naked conversion. I believe you're at the plug that has the switched low beam, green wire, where the bd43 kit snaps into. As you can see that green wire does not continue through the plug. I'll use your findings as an example.
It is actually a H4 bulb, as H4 are dual filament for a low and high beam function in one housing, which a lot of cars use. H7 is just single filament. I believe H4 is the only bulb type of the 7 varieties that have the dual.
