I've had mine in pieces for a few weeks now, the white 3 pin connector is for the stock tail lights (or at least, it looks identical to the ones I have.)
The green one is a bit more of a mystery, it looks the same style as the indicator connector (on the loom side of things) but on my SP1 the left indicator is a blue connector and the right one is orange. If I was in your situation I'd get a multimeter and start flicking switches to see if there's power to the pins and see where it's coming from.
Of course I could just be talking rubbish, but that's just my 2c.
