Scuba, the power connector you are looking for is really stuffed back in there, probably tucked in backwards towards the inside of the bike.. it takes a little fiddling around with to see in there. I took that panel you removed, widened the hole and installed a regular sized 12V plug in that spot, it was easy to connect the power to the battery directly with an inline fuse to that spot.
Alternatively I did install a FZ1 fuse block behind the left frame side cover and it works very well behind there. I even managed to fit an air compressor inside with the fuse block space as well.
